## Summary
- Moved `jsxSideEffects` (now `sideEffects`) from tsconfig.json compiler
options to the jsx object in the build API
- Updated all jsx bundler tests to use the new jsx.sideEffects
configuration
- Added jsx configuration parsing to JSBundler.zig
## Changes
- Removed jsxSideEffects parsing from `src/resolver/tsconfig_json.zig`
- Added jsx configuration parsing to `src/bun.js/api/JSBundler.zig`
Config.fromJS
- Fixed TransformOptions to properly pass jsx config to the transpiler
in `src/bundler/bundle_v2.zig`
- Updated TypeScript definitions to include jsx field in BuildConfigBase
- Modified test framework to support jsx configuration in API mode
- Updated all jsx tests to use `sideEffects` in the jsx config instead
of `side_effects` in tsconfig
## Test plan
All 27 jsx bundler tests are passing with the new configuration
structure.

# New features:
## Concurrent tests
Concurrent tests allow running multiple async tests at the same time.
```ts
// concurrent.test.ts
test.concurrent("this takes a while 1", async () => {
await Bun.sleep(1000);
});
test.concurrent("this takes a while 2", async () => {
await Bun.sleep(1000);
});
test.concurrent("this takes a while 3", async () => {
await Bun.sleep(1000);
});
```
Without `.concurrent`, this test file takes 3 seconds to run because
each one has to wait for the one before it to finish before it can
start.
With `.concurrent`, this file takes 1 second because all three sleeps
can run at once.
```
$> bun-after test concurrent
concurrent.test.js:
✓ this takes a while 1 [1005.36ms]
✓ this takes a while 2 [1012.51ms]
✓ this takes a while 3 [1013.15ms]
3 pass
0 fail
Ran 3 tests across 1 file. [1081.00ms]
```
To run all tests as concurrent, pass the `--concurrent` flag when
running tests.
Limitations:
- concurrent tests cannot attribute `expect()` call counts to the test,
meaning `expect.assertions()` does not function
- concurrent tests cannot use `toMatchSnapshot`. `toMatchInlineSnapshot`
is still supported.
- `beforeAll`/`afterAll` will never be executed concurrently.
`beforeEach`/`afterEach` will.
## Chaining
Chaining multiple describe/test qualifiers is now allowed. Previously,
it would fail.
```ts
// chaining-test-qualifiers.test.ts
test.failing.each([1, 2, 3])("each %i", async i => {
throw new Error(i);
});
```
```
$> bun-after test chaining-test-qualifiers
a.test.js:
✓ each 1
✓ each 2
✓ each 3
```
# Breaking changes:
## Describe ordering
Previously, describe callbacks were called immediately. Now, they are
deferred until the outer callback has finished running. The previous
order matched Jest. The new order is similar to Vitest, but does not
match exactly.
```ts
// describe-ordering.test.ts
describe("outer", () => {
console.log("outer before");
describe("inner", () => {
console.log("inner");
});
console.log("outer after");
});
```
Before, this would print
```
$> bun-before test describe-ordering
outer before
inner
outer after
```
Now, this will print
```
$> bun-after test describe-ordering
outer before
outer after
inner
```
## Test ordering
Describes are no longer always called before tests. They are now in
order.
```ts
// test-ordering.test.ts
test("one", () => {});
describe("scope", () => {
test("two", () => {});
});
test("three", () => {});
```
Before, this would print
```
$> bun-before test test-ordering
✓ scope > two
✓ one
✓ three
```
Now, this will print
```
$> bun-after test test-ordering
✓ one
✓ scope > two
✓ three
```
## Preload hooks
Previously, beforeAll in a preload ran before the first file and
afterAll ran after the last file. Now, beforeAll will run at the start
of each file and afterAll will run at the end of each file. This
behaviour matches Jest and Vitest.
```ts
// preload.ts
beforeAll(() => console.log("preload: beforeAll"));
afterAll(() => console.log("preload: afterAll"));
```
```ts
// preload-ordering-1.test.ts
test("demonstration file 1", () => {});
```
```ts
// preload-ordering-2.test.ts
test("demonstration file 2", () => {});
```
```
$> bun-before test --preload=./preload preload-ordering
preload-ordering-1.test.ts:
preload: beforeAll
✓ demonstration file 1
preload-ordering-2.test.ts:
✓ demonstration file 2
preload: afterAll
```
```
$> bun-after test --preload=./preload preload-ordering
preload-ordering-1.test.ts:
preload: beforeAll
✓ demonstration file 1
preload: afterAll
preload-ordering-2.test.ts:
preload: beforeAll
✓ demonstration file 2
preload: afterAll
```
## Describe failures
Current behaviour is that when an error is thrown inside a describe
callback, none of the tests declared there will run. Now, describes
declared inside will also not run. The new behaviour matches the
behaviour of Jest and Vitest.
```ts
// describe-failures.test.ts
describe("erroring describe", () => {
test("this test does not run because its describe failed", () => {
expect(true).toBe(true);
});
describe("inner describe", () => {
console.log("does the inner describe callback get called?");
test("does the inner test run?", () => {
expect(true).toBe(true);
});
});
throw new Error("uh oh!");
});
```
Before, the inner describe callback would be called and the inner test
would run, although the outer test would not:
```
$> bun-before test describe-failures
describe-failures.test.ts:
does the inner describe callback get called?
# Unhandled error between tests
-------------------------------
11 | throw new Error("uh oh!");
^
error: uh oh!
-------------------------------
✓ erroring describe > inner describe > does the inner test run?
1 pass
0 fail
1 error
1 expect() calls
Ran 1 test across 1 file.
Exited with code [1]
```
Now, the inner describe callback is not called at all.
```
$> bun-after test describe-failures
describe-failures.test.ts:
# Unhandled error between tests
-------------------------------
11 | throw new Error("uh oh!");
^
error: uh oh!
-------------------------------
0 pass
0 fail
1 error
Ran 0 tests across 1 file.
Exited with code [1]
```
## Hook failures
Previously, a beforeAll failure would skip subsequent beforeAll()s, the
test, and the afterAll. Now, a beforeAll failure skips any subsequent
beforeAll()s and the test, but not the afterAll.
```js
beforeAll(() => {
throw new Error("before all: uh oh!");
});
test("my test", () => {
console.log("my test");
});
afterAll(() => console.log("after all"));
```
```
$> bun-before test hook-failures
Error: before all: uh oh!
$> bun-after test hook-failures
Error: before all: uh oh!
after all
```
Previously, an async beforeEach failure would still allow the test to
run. Now, an async beforeEach failure will prevent the test from running
```js
beforeEach(() => {
await 0;
throw "uh oh!";
});
it("the test", async () => {
console.log("does the test run?");
});
```
```
$> bun-before test async-beforeeach-failure
does the test run?
error: uh oh!
uh oh!
✗ the test
$> bun-after test async-beforeeach-failure
error: uh oh!
uh oh!
✗ the test
```
## Hook timeouts
Hooks will now time out, and can have their timeout configured in an
options parameter
```js
beforeAll(async () => {
await Bun.sleep(1000);
}, 500);
test("my test", () => {
console.log("ran my test");
});
```
```
$> bun-before test hook-timeouts
ran my test
Ran 1 test across 1 file. [1011.00ms]
$> bun-after test hook-timeouts
✗ my test [501.15ms]
^ a beforeEach/afterEach hook timed out for this test.
```
## Hook execution order
beforeAll will now execute before the tests in the scope, rather than
immediately when it is called.
```ts
describe("d1", () => {
beforeAll(() => {
console.log("<d1>");
});
test("test", () => {
console.log(" test");
});
afterAll(() => {
console.log("</d1>");
});
});
describe("d2", () => {
beforeAll(() => {
console.log("<d2>");
});
test("test", () => {
console.log(" test");
});
afterAll(() => {
console.log("</d2>");
});
});
```
```
$> bun-before test ./beforeall-ordering.test.ts
<d1>
<d2>
test
</d1>
test
</d2>
$> bun-after test ./beforeall-ordering.test.ts
<d1>
test
</d1>
<d2>
test
</d2>
```
## test inside test
test() inside test() now errors rather than silently failing. Support
for this may be added in the future.
```ts
test("outer", () => {
console.log("outer");
test("inner", () => {
console.log("inner");
});
});
```
```
$> bun-before test
outer
✓ outer [0.06ms]
1 pass
0 fail
Ran 1 test across 1 file. [8.00ms]
$> bun-after test
outer
1 | test("outer", () => {
2 | console.log("outer");
3 | test("inner", () => {
^
error: Cannot call test() inside a test. Call it inside describe() instead.
✗ outer [0.71ms]
0 pass
1 fail
```
## afterAll inside test
afterAll inside a test is no longer allowed
```ts
test("test 1", () => {
afterAll(() => console.log("afterAll"));
console.log("test 1");
});
test("test 2", () => {
console.log("test 2");
});
```
```
$> bun-before
test 1
✓ test 1 [0.05ms]
test 2
✓ test 2
afterAll
$> bun-after
error: Cannot call afterAll() inside a test. Call it inside describe() instead.
✗ test 1 [1.00ms]
test 2
✓ test 2 [0.20ms]
```
# Only inside only
Previously, an outer 'describe.only' would run all tests inside it even
if there was an inner 'test.only'. Now, only the innermost only tests
are executed.
```ts
describe.only("outer", () => {
test("one", () => console.log("should not run"));
test.only("two", () => console.log("should run"));
});
```
```
$> bun-before test
should not run
should run
$> bun-after test
should run
```
With no inner only, the outer only will still run all tests:
```ts
describe.only("outer", () => {
test("test 1", () => console.log("test 1 runs"));
test("test 2", () => console.log("test 2 runs"));
});
```
# Potential follow-up work
- [ ] for concurrent tests, display headers before console.log messages
saying which test it is for
- this will need async context or similar
- refActiveExecutionEntry should also be able to know the current test
even in test.concurrent
- [ ] `test("rerun me", () => { console.log("run one time!"); });`
`--rerun-each=3` <- this runs the first and third time but not the
second time. fix.
- [ ] should to cache the JSValue created from
DoneCallback.callAsFunction
- [ ] implement retry and rerun params for tests.
- [ ] Remove finalizer on ScopeFunctions.zig by storing the data in 3
jsvalues passed in bind rather than using a custom class. We should also
migrate off of the ClassGenerator for ScopeFunctions
- [ ] support concurrent limit, how many concurrent tests are allowed to
run at a time. ie `--concurrent-limit=25`
- [ ] flag to run tests in random order
- [ ] `test.failing` should have its own style in the same way
`test.todo` passing marks as 'todo' insetead of 'passing'. right now
it's `✓` which is confusing.
- [ ] remove all instances of bun.jsc.Jest.Jest.current
- [ ] test options should be in BunTestRoot
- [ ] we will need one global still, stored in the globalobject/vm/?.
but it should not be a Jest instance.
- [ ] consider allowing test() inside test(), as well as afterEach and
afterAll. could even allow describe() too. to do this we would switch
from indices to pointers and they would be in a linked list. they would
be allocated in memorypools for perf/locality. some special
consideration is needed for making sure repeated tests lose their
temporary items. this could also improve memory usage soomewhat.
- [ ] consider using a jsc Bound Function rather than CallbackWithArgs.
bound functions allow adding arguments and they are only one value for
GC instead of many. and this removes our unnecessary three copies.
- [ ] eliminate Strong.Safe. we should be using a C++ class instead.
- [ ] consider modifying the junit reporter to print the whole describe
tree at the end instead of trying to output as test results come in. and
move it into its own file.
- [ ] expect_call_count/expect_assertions is confusing. rename to
`expect_calls`, `assert_expect_calls`. or something.
- [ ] Should make line_no be an enum with a none option and a function
to get if line nombers are enabled
- [ ] looks like we don't need to use file_id anymore (remove
`bun.jsc.Jest.Jest.runner.?.getOrPutFile(file_path).file_id;`, store the
file path directly)
- [ ] 'dot' test reporter like vitest?
- [ ] `test.failing.if(false)` errors because it can't replace mode
'failing' with mode 'skip'. this should probably be allowed instead.
- [ ] trigger timeout termination exception for `while(true) {}`
- [ ] clean up unused callbacks. as soon as we advance to the next
execution group, we can fully clean out the previous one. sometimes
within an execution sequence we can do the same.
- clean by swapping held values with undefined
- [ ] structure cache for performance for donecallback/scopefunctions
- [ ] consider migrating CallbackWithArgs to be a bound function. the
length of the bound function can exclude the specified args.
- [ ] setting both result and maybe_skip is not ideal, maybe there
should be a function to do both at once?
- [ ] try using a linked list rather than arraylist for describe/test
children, see how it affects performance
- [ ] consider a memory pool for describescope/executionentry. test if
it improves performance.
- [ ] consider making RefDataValue methods return the reason for failure
rather than ?value. that way we can improve error messages. the reason
could be a string or it could be a defined error set
- [ ] instead of 'description orelse (unnamed)', let's have description
default to 'unnamed' and not free it if it === the global that defines
that
- [ ] Add a phase before ordering results that inherits properties to
the parents. (eg inherit only from the child and inherit has_callback
from the child. and has_callback can be on describe/test individually
rather than on base). then we won't have that happening in an init()
function (terrible!)
- [ ] this test was incidentally passing because resolves.pass() wasn't
waiting for promise
```
test("fetching with Request object - issue #1527", async () => {
const server = createServer((req, res) => {
res.end();
}).listen(0);
try {
await once(server, "listening");
const body = JSON.stringify({ foo: "bar" });
const request = new Request(`http://localhost:${server.address().port}`,
{
method: "POST",
body,
});
expect(fetch(request)).resolves.pass();
} finally {
server.closeAllConnections();
}
});
```
- [ ] the error "expect.assertions() is not supported in the describe
phase, in concurrent tests, between tests, or after test execution has
completed" is not very good. we should be able to identify which of
those it is and print the right error for the context
- [ ] consider: instead of storing weak pointers to BunTest, we can
instead give the instance an id and check that it is correct when
getting the current bun test instance from the ref
- [ ] auto_killer: add three layers of auto_killer:
- preload (includes file & test)
- file (includes test)
- test
- that way at the end of the test, we kill the test processes. at the
end of the file, we kill the file processes. at the end of all, we kill
anything remaining.
AsyncLocalStorage
- store active_id & refdatavalue. active_id is a replacement for the
above weak pointers thing. refdatavalue is for determining which test it
is. this probably fits in 2×u64
- use for auto_killer so timeouts can kill even in concurrent tests

## Summary
Implements the Redis `HGET` command which returns a single hash field
value directly, avoiding the need to destructure arrays when retrieving
individual fields.
Requested by user who pointed out that currently you have to use `HMGET`
which returns an array even for single values.
## Changes
- Add native `HGET` implementation in `js_valkey_functions.zig`
- Export function in `js_valkey.zig`
- Add JavaScript binding in `valkey.classes.ts`
- Add TypeScript definitions in `redis.d.ts`
- Add comprehensive tests demonstrating the difference
## Motivation
Currently, to get a single hash field value:
```js
// Before - requires array destructuring
const [value] = await redis.hmget("key", ["field"]);
```
With this PR:
```js
// After - direct value access
const value = await redis.hget("key", "field");
```
## Test Results
All tests passing locally with Redis server:
- ✅ Returns single values (not arrays)
- ✅ Returns `null` for non-existent fields/keys
- ✅ Type definitions work correctly
- ✅ ~2x faster than HMGET for single field access
## Notes
This follows the exact same pattern as existing hash commands like
`HMGET`, just simplified for the single-field case. The Redis `HGET`
command has been available since Redis 2.0.0.

## Summary
- Removes unused function and class expression names when
`--minify-syntax` is enabled during bundling
- Adds `--keep-names` flag to preserve original names when minifying
- Matches esbuild's minification behavior
## Problem
When minifying with `--minify-syntax`, Bun was keeping function and
class expression names even when they were never referenced, resulting
in larger bundle sizes compared to esbuild.
**Before:**
```js
export var AB = function A() { };
// Bun output: var AB = function A() {};
// esbuild output: var AB = function() {};
```
## Solution
This PR adds logic to remove unused function and class expression names
during minification, matching esbuild's behavior. Names are only removed
when:
- `--minify-syntax` is enabled
- Bundling is enabled (not transform-only mode)
- The scope doesn't contain direct eval (which could reference the name
dynamically)
- The symbol's usage count is 0
Additionally, a `--keep-names` flag has been added to preserve original
names when desired (useful for debugging or runtime reflection).
## Testing
- Updated existing test in `bundler_minify.test.ts`
- All transpiler tests pass
- Manually verified output matches esbuild for various cases
## Examples
```bash
# Without --keep-names (names removed)
bun build --minify-syntax input.js
# var AB = function() {}
# With --keep-names (names preserved)
bun build --minify-syntax --keep-names input.js
# var AB = function A() {}
```

### What does this PR do?
The goal of this PR is to introduce PUB/SUB functionality to the
built-in Redis client. Based on the fact that the current Redis API does
not appear to have compatibility with `io-redis` or `redis-node`, I've
decided to do away with existing APIs and API compatibility with these
existing libraries.
I have decided to base my implementation on the [`redis-node` pub/sub
API](https://github.com/redis/node-redis/blob/master/docs/pub-sub.md).
### How did you verify your code works?
I've written a set of unit tests to hopefully catch the major use-cases
of this feature. They all appear to pass:
<img width="368" height="71" alt="image"
src="https://github.com/user-attachments/assets/36527386-c8fe-47f6-b69a-a11d4b614fa0"
/>
#### Future Improvements
I would have a lot more confidence in our Redis implementation if we
tested it with a test suite running over a network which emulates a high
network failure rate. There are large amounts of edge cases that are
worthwhile to grab, but I think we can roll that out in a future PR.
### Future Tasks
- [ ] Tests over flaky network
- [ ] Use the custom private members over `_<member>`.

### What does this PR do?
Remove incorrect jsdoc. A user was mislead by the docblocks
in the `ffi.d.ts` file
https://github.com/oven-sh/bun/issues/22289#issuecomment-3250221597 and
this PR attempts to fix that.
### How did you verify your code works?
Tests already appear to exist for all of these types in `ffi.test.js`.
## Summary
- Add `vi` export to `bun:test` TypeScript definitions for **partial**
Vitest compatibility
- Provides Vitest-style mocking API aliases for existing Jest functions
## Changes
Added `vi` object export in `packages/bun-types/test.d.ts` with
TypeScript interface for the methods Bun actually supports.
**Note**: This is a **limited subset** of Vitest's full `vi` API. Bun
currently implements only these 5 methods:
✅ **Implemented in Bun:**
- `vi.fn()` - Create mock functions (alias for `jest.fn`)
- `vi.spyOn()` - Create spies (alias for `spyOn`)
- `vi.module()` - Mock modules (alias for `mock.module`)
- `vi.restoreAllMocks()` - Restore all mocks (alias for
`jest.restoreAllMocks`)
- `vi.clearAllMocks()` - Clear mock state (alias for
`jest.clearAllMocks`)
❌ **NOT implemented** (full Vitest supports ~30+ methods):
- Timer mocking (`vi.useFakeTimers`, `vi.advanceTimersByTime`, etc.)
- Environment mocking (`vi.stubEnv`, `vi.stubGlobal`, etc.)
- Advanced module mocking (`vi.doMock`, `vi.importActual`, etc.)
- Utility methods (`vi.waitFor`, `vi.hoisted`, etc.)
## Test plan
- [x] Verified `vi` can be imported: `import { vi } from "bun:test"`
- [x] Tested all 5 implemented `vi` methods work correctly
- [x] Confirmed TypeScript types work with generics and proper type
inference
- [x] Validated compatibility with basic Vitest usage patterns
## Migration Benefits
This enables easier migration for **simple** Vitest tests that only use
basic mocking:
```typescript
// Basic Vitest tests work in Bun now
import { vi } from 'bun:test' // Previously would fail
const mockFn = vi.fn() // ✅ Works
const spy = vi.spyOn(obj, 'method') // ✅ Works
vi.clearAllMocks() // ✅ Works
// Advanced Vitest features still need porting to Jest-style APIs
// vi.useFakeTimers() // ❌ Not supported yet
// vi.stubEnv() // ❌ Not supported yet
```
This is a first step toward Vitest compatibility - more advanced
features would need additional implementation in Bun core.

### What does this PR do?
This PR adds `Bun.YAML.stringify`. The stringifier will double quote
strings only when necessary (looks for keywords, numbers, or containing
non-printable or escaped characters). Anchors and aliases are detected
by object equality, and anchor name is chosen from property name, array
item, or the root collection.
```js
import { YAML } from "bun"
YAML.stringify(null) // null
YAML.stringify("hello YAML"); // "hello YAML"
YAML.stringify("123.456"); // "\"123.456\""
// anchors and aliases
const userInfo = { name: "bun" };
const obj = { user1: { userInfo }, user2: { userInfo } };
YAML.stringify(obj, null, 2);
// # output
// user1:
// userInfo:
// &userInfo
// name: bun
// user2:
// userInfo:
// *userInfo
// will handle cycles
const obj = {};
obj.cycle = obj;
YAML.stringify(obj, null, 2);
// # output
// &root
// cycle:
// *root
// default no space
const obj = { one: { two: "three" } };
YAML.stringify(obj);
// # output
// {one: {two: three}}
```
### How did you verify your code works?
Added tests for basic use and edgecases
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit
- New Features
- Added YAML.stringify to the YAML API, producing YAML from JavaScript
values with quoting, anchors, and indentation support.
- Improvements
- YAML.parse now accepts a wider range of inputs, including Buffer,
ArrayBuffer, TypedArrays, DataView, Blob/File, and SharedArrayBuffer,
with better error propagation and stack protection.
- Tests
- Extensive new tests for YAML.parse and YAML.stringify across data
types, edge cases, anchors/aliases, deep nesting, and round-trip
scenarios.
- Chores
- Added a YAML stringify benchmark script covering multiple libraries
and data shapes.

This PR adds `Bun.secrets`, a new API for securely storing and
retrieving credentials using the operating system's native credential
storage locally. This helps developers avoid storing sensitive data in
plaintext config files.
```javascript
// Store a GitHub token securely
await Bun.secrets.set({
service: "my-cli-tool",
name: "github-token",
value: "ghp_xxxxxxxxxxxxxxxxxxxx"
});
// Retrieve it when needed
const token = await Bun.secrets.get({
service: "my-cli-tool",
name: "github-token"
});
// Use with fallback to environment variable
const apiKey = await Bun.secrets.get({
service: "my-app",
name: "api-key"
}) || process.env.API_KEY;
```
Marking this as a draft because Linux and Windows have not been manually
tested yet. This API is only really meant for local development usecases
right now, but it would be nice if in the future to support adapters for
production or CI usecases.
### Core API
- `Bun.secrets.get({ service, name })` - Retrieve a stored credential
- `Bun.secrets.set({ service, name, value })` - Store or update a
credential
- `Bun.secrets.delete({ service, name })` - Delete a stored credential
### Platform Support
- **macOS**: Uses Keychain Services via Security.framework
- **Linux**: Uses libsecret (works with GNOME Keyring, KWallet, etc.)
- **Windows**: Uses Windows Credential Manager via advapi32.dll
### Implementation Highlights
- Non-blocking - all operations run on the threadpool
- Dynamic loading - no hard dependencies on system libraries
- Sensitive data is zeroed after use
- Consistent API across all platforms
## Use Cases
This API is particularly useful for:
- CLI tools that need to store authentication tokens
- Development tools that manage API keys
- Any tool that currently stores credentials in `~/.npmrc`,
`~/.aws/credentials` or in environment variables that're globally loaded
## Testing
Comprehensive test suite included with coverage for:
- Basic CRUD operations
- Empty strings and special characters
- Unicode support
- Concurrent operations
- Error handling
All tests pass on macOS. Linux and Windows implementations are complete
but would benefit from additional platform testing.
## Documentation
- Complete API documentation in `docs/api/secrets.md`
- TypeScript definitions with detailed JSDoc comments and examples

### What does this PR do?
This PR adds builtin YAML parsing with `Bun.YAML.parse`
```js
import { YAML } from "bun";
const items = YAML.parse("- item1");
console.log(items); // [ "item1" ]
```
Also YAML imports work just like JSON and TOML imports
```js
import pkg from "./package.yaml"
console.log({ pkg }); // { pkg: { name: "pkg", version: "1.1.1" } }
```
### How did you verify your code works?
Added some tests for YAML imports and parsed values.

This adds a new flag --bail to bun test. When set, it will stop running
tests after the first failure. This is useful for CI environments where
you want to fail fast.

<!-- **For code changes, please include automated tests**. Feel free to
uncomment the line below -->
<!-- I wrote automated tests -->
<!-- If JavaScript/TypeScript modules or builtins changed:
- [ ] I included a test for the new code, or existing tests cover it
- [ ] I ran my tests locally and they pass (`bun-debug test

<!-- If Zig files changed:
- [ ] I checked the lifetime of memory allocated to verify it's (1)
freed and (2) only freed when it should be
- [ ] I included a test for the new code, or an existing test covers it
- [ ] JSValue used outside of the stack is either wrapped in a
JSC.Strong or is JSValueProtect'ed
- [ ] I wrote TypeScript/JavaScript tests and they pass locally

<!-- If dependencies in tests changed:
- [ ] I made sure that specific versions of dependencies are used
instead of ranged or tagged versions
-->
<!-- If a new builtin ESM/CJS module was added:
- [ ] I updated Aliases in `module_loader.zig` to include the new module
- [ ] I added a test that imports the module

### What does this PR do?
Introduce `Bun.stripANSI`, a SIMD-accelerated drop-in replacement for
the popular `"strip-ansi"` package.
`Bun.stripANSI` performs >10x faster and fixes several bugs in
`strip-ansi`, like [this long-standing
one](https://github.com/chalk/strip-ansi/issues/43).
### How did you verify your code works?
There are tests that check the output of `strip-ansi` matches
`Bun.stripANSI`. For cases where `strip-ansi`'s behavior is incorrect,
the expected value is manually provided.

### What does this PR do?
On Linux, AbortSignal.timeout created a file descriptor for each timeout
and did not keep the event loop alive when a timer was active. This is
fixed.

### What does this PR do?
dropAllLocks causes Thread::yield several times which means more system
calls which means more thread switches which means slower

### What does this PR do?
Releasing heap access causes all the heap helper threads to wake up and
lock and then unlock futexes, but it's important to do that to ensure
finalizers run quickly.
That means releasing heap access is a balance between:
1. CPU usage
2. Memory usage
Not releasing heap access causes benchmarks like
https://github.com/oven-sh/bun/pull/14885 to regress due to finalizers
not being called quickly enough.
Releasing heap access too often causes high idle CPU usage.
For the following code:
```
setTimeout(() => {}, 10 * 1000)
```
command time -v when with defaultRemainingRunsUntilSkipReleaseAccess =
0:
>
> Involuntary context switches: 605
>
command time -v when with defaultRemainingRunsUntilSkipReleaseAccess =
5:
>
> Involuntary context switches: 350
>
command time -v when with defaultRemainingRunsUntilSkipReleaseAccess =
10:
>
> Involuntary context switches: 241
>
Also comapre the #14885 benchmark with different values.
The idea here is if you entered JS "recently", running any
finalizers that might've been waiting to be run is a good idea.
But if you haven't, like if the process is just waiting on I/O
then don't bother.
