robobun 70fa6af355 feat: add Bun.Archive API for creating and extracting tarballs (#25665) 
## Summary

- Adds new `Bun.Archive` API for working with tar archives
- `Bun.Archive.from(data)` - Create archive from object, Blob,
TypedArray, or ArrayBuffer
- `Bun.Archive.write(path, data, compress?)` - Write archive to disk
(async)
- `archive.extract(path)` - Extract to directory, returns
`Promise<number>` (file count)
- `archive.blob(compress?)` - Get archive as Blob (async)
- `archive.bytes(compress?)` - Get archive as Uint8Array (async)

Key implementation details:
- Uses existing libarchive bindings for tarball creation/extraction via
`extractToDisk`
- Uses libdeflate for gzip compression
- Immediate byte copying for GC safety (no JSValue protection, no
`hasPendingActivity`)
- Async operations run on worker pool threads with proper VM reference
handling
- Growing memory buffer via `archive_write_open2` callbacks for
efficient tarball creation

## Test plan

- [x] 65 comprehensive tests covering:
  - Normal operations (create, extract, blob, bytes, write)
  - GC safety (unreferenced archives, mutation isolation)  
  - Error handling (invalid args, corrupted data, I/O errors)
- Edge cases (large files, many files, special characters, path
normalization)
  - Concurrent operations
