fix: respect install.lockfile.save=false when migrating from package-lock.json

Previously, Bun would always save a lockfile when migrating from package-lock.json
or yarn.lock, even when install.lockfile.save was set to false in bunfig.toml.
This fix ensures that the save=false configuration is respected during migration.

The lockfile is still migrated and used in memory for dependency resolution,
but it is not written to disk when save=false.

Fixes #22963

 - `internal/` - Internal modules not exposed to users
 - `builtins/` - Core JavaScript builtins (streams, console, etc.)
 
+### Special Syntax in Built-in Modules
+
+1. **`$` prefix** - Access to private properties and JSC intrinsics:
+
+   ```js
+   const arr = $Array.from(...);  // Private global
+   map.$set(...);                 // Private method
+   const arr2 = $newArrayWithSize(5); // JSC intrinsic

+
+2. **`require()`** - Must use string literals, resolved at compile time:
+
+   ```js
+   const fs = require("fs"); // Directly loads by numeric ID
+   ```
+
+3. **Debug helpers**:
+   - `$debug()` - Like console.log but stripped in release builds
+   - `$assert()` - Assertions stripped in release builds
+   - `if($debug) {}` - Check if debug env var is set
+
+4. **Platform detection**: `process.platform` and `process.arch` are inlined and dead-code eliminated
+
+5. **Export syntax**: Use `export default` which gets converted to a return statement:
+   ```js
+   export default {
+     readFile,
+     writeFile,
+   };
+   ```
+
+Note: These are NOT ES modules. The preprocessor converts `$` to `@` (JSC's actual syntax) and handles the special functions.

-## Pub/Sub
-
-Bun provides native bindings for the [Redis
-Pub/Sub](https://redis.io/docs/latest/develop/pubsub/) protocol. **New in Bun
-1.2.23**
-
-{% callout %}
-**🚧** — The Redis Pub/Sub feature is experimental. Although we expect it to be
-stable, we're currently actively looking for feedback and areas for improvement.
-{% /callout %}
-
-### Basic Usage
-
-To get started publishing messages, you can set up a publisher in
-`publisher.ts`:
-
-```typescript#publisher.ts
-import { RedisClient } from "bun";
-
-const writer = new RedisClient("redis://localhost:6739");
-await writer.connect();
-
-writer.publish("general", "Hello everyone!");
-
-writer.close();
-```
-
-In another file, create the subscriber in `subscriber.ts`:
-
-```typescript#subscriber.ts
-import { RedisClient } from "bun";
-
-const listener = new RedisClient("redis://localhost:6739");
-await listener.connect();
-
-await listener.subscribe("general", (message, channel) => {
-  console.log(`Received: ${message}`);
-});
-```
-
-In one shell, run your subscriber:
-
-```bash
-bun run subscriber.ts
-```
-
-and, in another, run your publisher:
-
-```bash
-bun run publisher.ts
-```
-
-{% callout %}
-**Note:** The subscription mode takes over the `RedisClient` connection. A
-client with subscriptions can only call `RedisClient.prototype.subscribe()`. In
-other words, applications which need to message Redis need a separate
-connection, acquirable through `.duplicate()`:
-
-```typescript
-import { RedisClient } from "bun";
-
-const redis = new RedisClient("redis://localhost:6379");
-await redis.connect();
-const subscriber = await redis.duplicate();
-
-await subscriber.subscribe("foo", () => {});
-await redis.set("bar", "baz");
-```
-
-{% /callout %}
-
-### Publishing
-
-Publishing messages is done through the `publish()` method:
-
-```typescript
-await client.publish(channelName, message);
-```
-
-### Subscriptions
-
-The Bun `RedisClient` allows you to subscribe to channels through the
-`.subscribe()` method:
-
-```typescript
-await client.subscribe(channel, (message, channel) => {});
-```
-
-You can unsubscribe through the `.unsubscribe()` method:
-
-```typescript
-await client.unsubscribe(); // Unsubscribe from all channels.
-await client.unsubscribe(channel); // Unsubscribe a particular channel.
-await client.unsubscribe(channel, listener); // Unsubscribe a particular listener.
-```

-```
-
-- `value`: The value to convert to YAML
-- `replacer`: Currently only `null` or `undefined` (function replacers not yet supported)
-- `space`: Number of spaces for indentation (e.g., `2`) or a string to use for indentation. **Without this parameter, outputs flow-style (single-line) YAML**
-
-#### Basic Usage
-
-```ts
-import { YAML } from "bun";
-
-const data = {
-  name: "John Doe",
-  age: 30,
-  hobbies: ["reading", "coding"],
-};
-

-console.log(YAML.stringify(arr, null, 2));
-// - 1
-// - 2
-// - 3
-```

-#### String Quoting
-
-`YAML.stringify()` automatically quotes strings when necessary:
-
-- Strings that would be parsed as YAML keywords (`true`, `false`, `null`, `yes`, `no`, etc.)
-- Strings that would be parsed as numbers
-- Strings containing special characters or escape sequences

-```ts
-const examples = {

-  number: "123", // Will be quoted: "123"
-  text: "hello world", // Won't be quoted: hello world
-  empty: "", // Will be quoted: ""

-// keyword: "true"
-// number: "123"
-// text: hello world
-// empty: ""
-```
-
-#### Cycles and References
-
-`YAML.stringify()` automatically detects and handles circular references using YAML anchors and aliases:
-
-```ts
-const obj = { name: "root" };
-obj.self = obj; // Circular reference
-
-const yamlString = YAML.stringify(obj, null, 2);
-console.log(yamlString);
-// &root
-// name: root
-// self:
-//   *root
-
-// Objects with shared references

-const data = {
-  first: shared,
-  second: shared,
-};
-

-//   &first
-//   id: 1
-// second:
-//   *first
-```
-
-#### Special Values
-

-### Configuration Migration
-
-The following pnpm configuration is migrated from both `pnpm-lock.yaml` and `pnpm-workspace.yaml`:
-
-- **Overrides**: Moved from `pnpm.overrides` to root-level `overrides` in `package.json`
-- **Patched Dependencies**: Moved from `pnpm.patchedDependencies` to root-level `patchedDependencies` in `package.json`
-- **Workspace Overrides**: Applied from `pnpm-workspace.yaml` to root `package.json`
-
-### Requirements
-
-- Requires pnpm lockfile version 7 or higher
-- Workspace packages must have a `name` field in their `package.json`
-- All catalog entries referenced by dependencies must exist in the catalogs definition
-
-After migration, you can safely remove `pnpm-lock.yaml` and `pnpm-workspace.yaml` files.

-
-```sh
-# Reproduce a previous randomized run
-$ bun test --seed 123456

 - **Dependencies can be de-duplicated.** If `a` and `b` share a common dependency, it will be _hoisted_ to the root `node_modules` directory. This reduces redundant disk usage and minimizes "dependency hell" issues associated with having multiple versions of a package installed simultaneously.

-
-# Run only unit tests (sequential)
-bun test tests/unit
-
-# Run only integration tests (concurrent due to glob pattern)
-bun test tests/integration
-```
-
-## Benefits
-
-1. **Gradual Migration**: Migrate to concurrent tests file by file by renaming them
-2. **Clear Organization**: File naming convention indicates execution mode
-3. **Performance**: Integration tests run faster in parallel
-4. **Safety**: Unit tests remain sequential where needed
-5. **Flexibility**: Easy to change execution mode by renaming files
-
-## Migration Strategy
-
-To migrate existing tests to concurrent execution:
-
-1. Start with independent integration tests
-2. Rename files to match the glob pattern: `mv api.test.ts concurrent-api.test.ts`
-3. Verify tests still pass
-4. Monitor for race conditions or shared state issues
-5. Continue migrating stable tests incrementally
-
-## Tips
-
-- Use descriptive prefixes: `concurrent-`, `parallel-`, `async-`
-- Keep related sequential tests together
-- Document why certain tests must remain sequential
-- Use `test.concurrent()` for fine-grained control in sequential files
-  (In files matched by `concurrentTestGlob`, plain `test()` already runs concurrently)
-- Consider separate globs for different test types:
-
-```toml
-[test]
-# Multiple patterns for different test categories
-concurrentTestGlob = [
-  "**/integration/*.test.ts",
-  "**/e2e/*.test.ts",
-  "**/concurrent-*.test.ts"
-]
-```
