b93468ca48 Fix ESM <> CJS dual-package hazard determinism bug (#22231)
### What does this PR do?

Originally, we attempted to avoid the "dual package hazard" right before
we enqueue a parse task, but that code gets called in a
non-deterministic order. This meant that some of your modules would use
the right variant and some of them would not.

We have to instead do that in a separate pass, after all the files are
parsed.

The thing to watch out for with this PR is how it impacts the dev
server.

### How did you verify your code works?

Unskipped tests. Plus manual.

35e9f3d4a2 Fix HTMLRewriter TextChunk null pointer crash (#22254)
## Summary

Fixes a crash with `panic: attempt to use null value` in
`html_rewriter.zig:1190` when accessing TextChunk properties after
HTMLRewriter cleanup.

The crash occurred in the `lastInTextNode` and `removed` methods when
they tried to dereference a null `text_chunk` pointer using
`this.text_chunk.?` without proper null checks.

## Root Cause

The TextChunk methods `removed()` and `lastInTextNode()` were missing
null checks that other methods like `getText()` and `remove()` already
had. When TextChunk objects are accessed after the HTMLRewriter
transformation completes and internal cleanup occurs, the `text_chunk`
pointer becomes null, causing a panic.

## Changes

- **src/bun.js/api/html_rewriter.zig**: 
- Add null check to `removed()` method - returns `false` when
`text_chunk` is null
- Add null check to `lastInTextNode()` method - returns `false` when
`text_chunk` is null
  
- **test/regression/issue/text-chunk-null-access.test.ts**: 
  - Add regression test that reproduces the original crash scenario
- Test verifies that accessing TextChunk properties after cleanup
returns sensible defaults instead of crashing

## Crash Reproduction

The regression test successfully reproduces the crash:

- **Regular `bun test`**:  CRASHES with `panic: attempt to use null
value`
- **With fix `bun bd test`**:  PASSES

## Test Plan

- [x] Existing HTMLRewriter tests still pass
- [x] New regression test passes with the fix
- [x] New regression test crashes without the fix (confirmed on regular
bun)
- [x] Both `removed` and `lastInTextNode` now return sensible defaults
(`false`) when called on cleaned up TextChunk objects

fe8f8242fd Make BoundedArray more compact, shrink Data in sql from 32 bytes to 24 bytes (#22210)
### What does this PR do?

- Instead of storing `len` in `BoundedArray` as a `usize`, store it as
either a `u8` or ` u16` depending on the `buffer_capacity`
- Copy-paste `BoundedArray` from the standard library into Bun's
codebase as it was removed in
https://github.com/ziglang/zig/pull/24699/files#diff-cbd8cbbc17583cb9ea5cc0f711ce0ad447b446e62ea5ddbe29274696dce89e4f

c69ed120e9 Rename some instances of latin1 to cp1252 (#22059)
in JS, `new TextDecoder("latin1").decode(...)` uses cp1252. In python,
latin1 is half-width utf-16. In our code, latin1 typically refers to
half-width utf-16 because JavaScriptCore uses that for most strings, but
sometimes it refers to cp1252. Rename the cp1252 functions to be called
cp1252

Also fixes an issue where Buffer.from with utf-16le would sometimes
output the wrong value:

```js
$> bun -p "Buffer.from('\x80', 'utf-16le')"
<Buffer ac 20>
$> node -p "Buffer.from('\x80', 'utf-16le')"
<Buffer 80 00>
$> bun-debug -p "Buffer.from('\x80', 'utf-16le')"
<Buffer 80 00>

edea077947 Fix env_loader allocator threading issue with BUN_INSPECT_CONNECT_TO (#22206)
## Summary
- Fixed allocator threading violation when `BUN_INSPECT_CONNECT_TO` is
set
- Created thread-local `env_loader` with proper allocator isolation in
debugger thread
- Added regression test to verify the fix works correctly

## Problem
When `BUN_INSPECT_CONNECT_TO` environment variable is set, Bun creates a
debugger thread that spawns its own `VirtualMachine` instance.
Previously, this VM would fall back to the global `DotEnv.instance`
which was created with the main thread's allocator, causing threading
violations when the debugger thread accessed environment files via
`--env-file` or other env loading operations.

## Solution
Modified `startJSDebuggerThread` in `src/bun.js/Debugger.zig` to:
1. Create a thread-local `DotEnv.Map` and `DotEnv.Loader` using the
debugger thread's allocator
2. Pass this thread-local `env_loader` to `VirtualMachine.init()` to
ensure proper allocator isolation
3. Prevent sharing of allocators across threads

## Test plan
- [x] Added regression test in
`test/regression/issue/test_env_loader_threading.test.ts`
- [x] Verified basic Bun functionality still works
- [x] Test passes with both normal execution and with
`BUN_INSPECT_CONNECT_TO` set

0315c97e7b Fix argv handling for standalone binaries - remove extra executable name (#22157) (#22169)
## Summary

Fixes an issue where compiled standalone binaries included an extra
executable name argument in `process.argv`, breaking code that uses
`node:util.parseArgs()` with `process.argv.slice(2)`.

## Problem

When running a compiled binary, `process.argv` incorrectly included the
executable name as a third argument:

```bash
./my-app
# process.argv = ["bun", "/$bunfs/root/my-app", "./my-app"]  # BUG
```

This caused `parseArgs()` to fail with "Unexpected argument" errors,
breaking previously valid code.

## Solution

Fixed the `offset_for_passthrough` calculation in `cli.zig` to always
skip the executable name for standalone binaries, ensuring
`process.argv` only contains the runtime name and script path:

```bash  
./my-app
# process.argv = ["bun", "/$bunfs/root/my-app"]  # FIXED
```

## Test plan

- [x] Added regression test in `test/regression/issue/22157.test.ts`
- [x] Verified existing exec-argv functionality still works correctly  
- [x] Manual testing confirms the fix resolves the parseArgs issue

Fixes #22157

f718f4a312 Fix argv handling for standalone binaries with compile-exec-argv (#22084)
## Summary

Fixes an issue where `--compile-exec-argv` options were incorrectly
appearing in `process.argv` when no user arguments were provided to a
compiled standalone binary.

## Problem

When building a standalone binary with `--compile-exec-argv`, the exec
argv options would leak into `process.argv` when running the binary
without any user arguments:

```bash
# Build with exec argv
bun build --compile-exec-argv="--user-agent=hello" --compile ./a.js

# Run without arguments - BEFORE fix
./a
# Output showed --user-agent=hello in both execArgv AND argv (incorrect)
{
  execArgv: [ "--user-agent=hello" ],
  argv: [ "bun", "/$bunfs/root/a", "--user-agent=hello" ],  # <- BUG: exec argv leaked here
}

# Expected behavior (matches runtime):
bun --user-agent=hello a.js
{
  execArgv: [ "--user-agent=hello" ],
  argv: [ "/path/to/bun", "/path/to/a.js" ],  # <- No exec argv in process.argv
}
```

## Solution

The issue was in the offset calculation for determining which arguments
to pass through to the JavaScript runtime. The offset was being
calculated before modifying the argv array with exec argv options,
causing it to be incorrect when the original argv only contained the
executable name.

The fix ensures that:
- `process.execArgv` correctly contains the compile-exec-argv options
- `process.argv` only contains the executable, script path, and user
arguments
- exec argv options never leak into `process.argv`

## Test plan

Added comprehensive tests to verify:
1. Exec argv options don't leak into process.argv when no user arguments
are provided
2. User arguments are properly passed through when exec argv is present
3. Existing behavior continues to work correctly

All tests pass:
```
bun test compile-argv.test.ts
✓ 3 tests pass
```

707fc4c3a2 Introduce Bun.secrets API (#21973)
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

8fad98ffdb Add Bun.YAML.parse and YAML imports (#22073)
### 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.

75f0ac4395 Add Windows metadata flags to bun build --compile (#22067)
## Summary
- Adds support for setting Windows executable metadata through CLI flags
when using `bun build --compile`
- Implements efficient single-operation metadata updates using the
rescle library
- Provides comprehensive error handling and validation

## New CLI Flags
- `--windows-title`: Set the application title
- `--windows-publisher`: Set the publisher/company name  
- `--windows-version`: Set the file version (e.g. "1.0.0.0")
- `--windows-description`: Set the file description
- `--windows-copyright`: Set the copyright notice

## JavaScript API
These options are also available through the `Bun.build()` JavaScript
API:
```javascript
await Bun.build({
  entrypoints: ["./app.js"],
  outfile: "./app.exe",
  compile: true,
  windows: {
    title: "My Application",
    publisher: "My Company",
    version: "1.0.0.0",
    description: "Application description",
    copyright: "© 2025 My Company"
  }
});
```

## Implementation Details
- Uses a unified `rescle__setWindowsMetadata` C++ function that loads
the Windows executable only once for efficiency
- Properly handles UTF-16 string conversion for Windows APIs
- Validates version format (supports "1", "1.2", "1.2.3", or "1.2.3.4"
formats)
- Returns specific error codes for better debugging
- All operations return errors instead of calling `Global.exit(1)`

## Test Plan
Comprehensive test suite added in
`test/bundler/compile-windows-metadata.test.ts` covering:
- All CLI flags individually and in combination
- JavaScript API usage
- Error cases (invalid versions, missing --compile flag, etc.)
- Special character handling in metadata strings

All 20 tests passing (1 skipped as not applicable on Windows).

7717693c70 Dev server refactoring, part 1 (mainly IncrementalGraph) (#22010)
* `IncrementalGraph(.client).File` packs its fields in a specific way to
save space, but it makes the struct hard to use and error-prone (e.g.,
untagged unions with tags stored in a separate `flags` struct). This PR
changes `File` to have a human-readable layout, but adds methods to
convert it to and from `File.Packed`, a packed version with the same
space efficiency as before.
* Reduce the need to pass the dev allocator to functions (e.g.,
`deinit`) by storing it as a struct field via the new `DevAllocator`
type. This type has no overhead in release builds, or when
`AllocationScope` is disabled.
* Use owned pointers in `PackedMap`.
* Use `bun.ptr.Shared` for `PackedMap` instead of the old
`bun.ptr.RefPtr`.
* Add `bun.ptr.ScopedOwned`, which is like `bun.ptr.Owned`, but can
store an `AllocationScope`. No overhead in release builds or when
`AllocationScope` is disabled.
* Reduce redundant allocators in `BundleV2`.
* Add owned pointer conversions to `MutableString`.
* Make `AllocationScope` behave like a pointer, so it can be moved
without invalidating allocations. This eliminates the need for
self-references.
* Change memory cost algorithm so it doesn't rely on “dedupe bits”.
These bits used to take advantage of padding but there is now no padding
in `PackedMap`.
* Replace `VoidFieldTypes` with `useAllFields`; this eliminates the need
for `voidFieldTypesDiscardHelper`.

790e5d4a7e fix: prevent assertion failure when stopping server with pending requests (#22070)
## Summary

Fixes an assertion failure that occurred when `server.stop()` was called
while HTTP requests were still in flight.

## Root Cause

The issue was in `jsValueAssertAlive()` at
`src/bun.js/api/server.zig:627`, which had an assertion requiring
`server.listener != null`. However, `server.stop()` immediately sets
`listener` to null, causing assertion failures when pending requests
triggered callbacks that accessed the server's JavaScript value.

## Solution

Converted the server's `js_value` from `jsc.Strong.Optional` to
`jsc.JSRef` for safer lifecycle management:

- **On `stop()`**: Downgrade from strong to weak reference instead of
calling `deinit()`
- **In `finalize()`**: Properly call `deinit()` on the JSRef  
- **Remove problematic assertion**: JSRef allows safe access to JS value
via weak reference even after stop

## Benefits

-  No more assertion failures when stopping servers with pending
requests
-  In-flight requests can still access the server JS object safely  
-  JS object can be garbage collected when appropriate
-  Maintains backward compatibility - no external API changes

## Test plan

- [x] Reproduces the original assertion failure
- [x] Verifies the fix resolves the issue
- [x] Adds regression test to prevent future occurrences
- [x] Confirms normal server functionality still works

The fix includes a comprehensive regression test at
`test/regression/issue/server-stop-with-pending-requests.test.ts`.

b2351bbb4e Add Symbol.asyncDispose to Worker in worker_threads (#22064)
## Summary

- Implement `Symbol.asyncDispose` for the `Worker` class in
`worker_threads` module
- Enables automatic resource cleanup with `await using` syntax
- Calls `await this.terminate()` to properly shut down workers when they
go out of scope

## Implementation Details

The implementation adds a simple async method to the Worker class:

```typescript
async [Symbol.asyncDispose]() {
  await this.terminate();
}
```

This allows workers to be used with the new `await using` syntax for
automatic cleanup:

```javascript
{
  await using worker = new Worker('./worker.js');
  // worker automatically terminates when leaving this scope
}
```

## Test Plan

- [x] Added comprehensive tests for `Symbol.asyncDispose` functionality
- [x] Tests verify the method exists and returns undefined
- [x] Tests verify `await using` syntax works correctly for automatic
worker cleanup
- [x] All new tests pass
- [x] Existing worker_threads functionality remains intact

92b38fdf80 sql: support array of strings in SQLHelper (#21572)
### What does this PR do?
Support the following:
```javascript
const nom = await sql`SELECT name FROM food WHERE category IN ${sql(['bun', 'baozi', 'xiaolongbao'])}`;
```

Previously, only e.g., `sql([1, 2, 3])` was supported.

To be honest I'm not sure what the semantics of SQLHelper *ought* to be.
I'm pretty sure objects ought to be auto-inferred. I'm not sure about
arrays, but given the rest of the code in `SQLHelper` trying to read the
tea leaves on stringified numeric keys I figured someone cared about
this use case. I don't know about other types, but I'm pretty sure that
`Object.keys("bun") === [0, 1, 2]` is an oversight and unintended.
(Incidentally, the reason numbers previously worked is because
`Object.keys(4) === []`). I decided that all non-objects and non-arrays
should be treated as not having auto-inferred columns.

Fixes #18637 

### How did you verify your code works?
I wrote a test, but was unable to run it (or any other tests in this
file) locally due to Docker struggles. I sure hope it works!

e3e8d15263 Fix redis reconnecting (#21724)
### What does this PR do?

This PR fixes https://github.com/oven-sh/bun/issues/19131.

I am not 100% certain that this fix is correct as I am still nebulous
regarding some decisions I've made in this PR. I'll try to provide my
reasoning and would love to be proven wrong:

#### Re-authentication

- The `is_authenticated` flag needs to be reset to false. When the
lifecycle reaches a point of attempting to connect, it sends out a
`HELLO 3`, and receives a response. `handleResponse()` is fired and does
not correctly handle it because there is a guard at the top of the
function:

```zig
if (!this.flags.is_authenticated) {
    this.handleHelloResponse(value);

    // We've handled the HELLO response without consuming anything from the command queue
    return;
}
```

Rather, it treats this packet as a regular data packet and complains
that it doesn't have a promise to associate it to. By resetting the
`is_authenticated` flag to false, we guarantee that we handle the `HELLO
3` packet as an authentication packet.

It also seems to make semantic sense since dropping a connection implies
you dropped authentication.

#### Retry Attempts

I've deleted the `retry_attempts = 0` in `reconnect()` because I noticed
that we would never actually re-attempt to reconnect after the first
attempt. Specifically, I was expecting `valkey.zig:459` to potentially
fire multiple times, but it only ever fired once. Removing this reset to
zero caused successful reattempts (in my case 3 of them).

```zig
        debug("reconnect in {d}ms (attempt {d}/{d})", .{ delay_ms, this.retry_attempts, this.max_retries });
```

I'm still iffy on whether this is necessary, but I think it makes sense.
```zig
        this.client.retry_attempts = 0
```

### How did you verify your code works?

I have added a small unit test. I have compared mainline `bun`, which
fails that test, to this fix, which passes the test.

e7672b2d04 Add string fast path for postMessage and structuredClone (#21926)
## Summary

Implements a string fast path optimization for `postMessage` and
`structuredClone` operations that provides significant performance
improvements for string-only data transfer, along with various bug fixes
and infrastructure improvements.

## Key Performance Improvements

**postMessage with Workers:**
- **Small strings (11 chars):** ~5% faster (572ns vs 599ns)
- **Medium strings (14KB):** **~2.7x faster** (528ns vs 1.40μs) 
- **Large strings (3MB):** **~660x faster** (540ns vs 356μs)

**Compared to Node.js postMessage:**
- Similar performance for small strings
- Competitive for medium strings  
- **~455x faster** for large strings (540ns vs 245μs)

## Implementation Details

The optimization adds a **string fast path** that bypasses full
structured cloning serialization when:
- Input is a pure string (`value.isString()`)
- No transfer list or message ports are involved
- Not being stored persistently

### Core Changes

**String Thread-Safety Utilities (`BunString.cpp/h`):**
- `isCrossThreadShareable()` - Checks if string can be safely shared
across threads
- `toCrossThreadShareable()` - Converts strings to thread-safe form via
`isolatedCopy()`
- Handles edge cases: atoms, symbols, substring slices, external buffers

**Serialization Fast Path (`SerializedScriptValue.cpp`):**
- New `m_fastPathString` field stores string data directly
- Bypasses full object serialization machinery for pure strings
- Creates isolated copies for cross-thread safety

**Deserialization Fast Path:**
- Directly returns JSString from stored string data
- Avoids parsing serialized byte streams

**Updated Flags System (`JSValue.zig`, `Serialization.cpp`):**
- Replaces boolean `forTransfer` with structured `SerializedFlags`
- Supports `forCrossProcessTransfer` and `forStorage` distinctions

**Structured Clone Infrastructure:**
- Moved `structuredClone` implementation to dedicated
`StructuredClone.cpp`
- Added `jsFunctionStructuredCloneAdvanced` for testing with custom
flags
- Improved class serialization compatibility checks (`isForTransfer`,
`isForStorage`)

**IPC Improvements (`ipc.zig`):**
- Fixed race conditions in `SendQueue` by deferring cleanup to next tick
- Proper fd ownership handling with `bun.take()`
- Cached IPC serialize/parse functions for better performance

**BlockList Thread Safety Fixes (`BlockList.zig`):**
- Fixed potential deadlocks by moving mutex locking inside methods
- Added atomic `estimated_size` counter to avoid lock during GC
- Corrected pointer handling in comparison functions
- Improved GC safety in `rules()` method

## Benchmark Results

```
❯ bun-21926 bench/string-postmessage.mjs  # This branch
postMessage(11 chars string)  572.24 ns/iter
postMessage(14 KB string)     527.55 ns/iter  ← ~2.7x faster
postMessage(3 MB string)      539.70 ns/iter  ← ~660x faster

❯ bun-1.2.20 bench/string-postmessage.mjs  # Previous
postMessage(11 chars string)  598.76 ns/iter
postMessage(14 KB string)       1.40 µs/iter
postMessage(3 MB string)      356.38 µs/iter

❯ node bench/string-postmessage.mjs       # Node.js comparison  
postMessage(11 chars string)  569.63 ns/iter
postMessage(14 KB string)       1.46 µs/iter
postMessage(3 MB string)      245.46 µs/iter
```

**Key insight:** The fast path achieves **constant time performance**
regardless of string size (~540ns), while traditional serialization
scales linearly with data size.

## Test Coverage

**New Tests:**
- `test/js/web/structured-clone-fastpath.test.ts` - Fast path memory
usage validation
- `test/js/web/workers/structuredClone-classes.test.ts` - Comprehensive
class serialization tests
  - Tests ArrayBuffer transferability 
  - Tests BunFile cloning with storage/transfer restrictions
  - Tests net.BlockList cloning behavior
  - Validates different serialization contexts (default, worker, window)

**Enhanced Tests:**
- `test/js/web/workers/structured-clone.test.ts` - Multi-function
testing
- Tests `structuredClone`, `jscSerializeRoundtrip`, and cross-process
serialization
  - Validates consistency across different serialization paths
- `test/js/node/cluster.test.ts` - Better error handling and debugging

**Benchmarks:**
- `bench/string-postmessage.mjs` - Worker postMessage performance
comparison
- `bench/string-fastpath.mjs` - Fast path vs traditional serialization
comparison

## Bug Fixes

**BlockList Threading Issues:**
- Fixed potential deadlocks when multiple threads access BlockList
simultaneously
- Moved mutex locks inside methods rather than holding across entire
function calls
- Added atomic size tracking for GC compatibility
- Fixed comparison function pointer handling

**IPC Race Conditions:**
- Fixed race condition where `SendQueue._onAfterIPCClosed()` could be
called on wrong thread
- Deferred cleanup operations to next tick using task queue
- Improved file descriptor ownership with proper `bun.take()` usage

**Structured Clone Compatibility:**
- Enhanced class serialization with proper transfer/storage mode
checking
- Fixed edge cases where non-transferable objects were incorrectly
handled
- Added better error reporting for unsupported clone operations

## Technical Notes

- Thread safety ensured via `String.isolatedCopy()` for cross-VM
transfers
- Memory cost calculation updated to account for string references
- Maintains full compatibility with existing structured clone semantics
- Does not affect object serialization or transfer lists
- Proper cleanup and error handling throughout IPC pipeline

7110dc10a4 Fix UTF-16 encoding crash with odd-length byte arrays (#21966)
## Summary
- Fixes a panic: "exact division produced remainder" that occurs when
reading files with odd number of bytes using utf16le/ucs2 encoding
- The crash happened in `encoding.zig:136` when
`std.mem.bytesAsSlice(u16, input)` was called on a byte slice with odd
length
- Fixed by properly checking for odd-length input and truncating to the
nearest even length

## Test plan
- Added regression tests in
`test/regression/issue/utf16-encoding-crash.test.ts`
- Tests verify that reading files with odd byte counts doesn't crash
- Tests verify correct truncation behavior matches Node.js expectations
- Verified edge cases (0, 1 byte inputs) return empty strings

## Root Cause
The original code checked `if (input.len / 2 == 0)` which only caught 0
and 1-byte inputs, but `std.mem.bytesAsSlice(u16, input)` panics on any
odd-length input (3, 5, 7, etc. bytes).

## Fix Details
- Changed condition to check `input.len % 2 != 0` for any odd length
- Truncate odd-length inputs to the nearest even length for valid UTF-16
processing
- Handle edge cases by returning empty string for 0 or 1-byte inputs

f5ef9cda3c Fix panic in JavaScript lexer when parsing invalid template strings in JSX (#21967)
## Summary

- Fixes a crash where invalid slice bounds caused a panic with message:
"start index N is larger than end index M"
- The issue occurred in `js_lexer.zig:767` when calculating string
literal content slice bounds
- Adds proper bounds checking to prevent slice bounds violations
- Includes regression test to prevent future occurrences

## Root Cause

The crash happened when `suffix_len` was larger than `lexer.end`,
causing the calculation `lexer.end - suffix_len` to result in a value
smaller than the `base` position. This created invalid slice bounds like
`[114..113]`.

## Solution

Added bounds checking to ensure:
1. `end_pos` is calculated safely: `if (lexer.end >= suffix_len)
lexer.end - suffix_len else lexer.end`
2. `slice_end` is always >= `base`: `@max(base, end_pos)`

## Test Plan

- [x] Added regression test in
`test/regression/issue/jsx-template-string-crash.test.ts`
- [x] Test verifies no crashes occur with JSX template string patterns
- [x] Verified normal template string functionality still works
- [x] All tests pass
