Pull request overview
This pull request updates oxc dependencies from v0.112.0/v0.113.0 to v0.114.0 across both the JavaScript/TypeScript and Rust ecosystems. The update requires code adaptations to accommodate breaking changes in oxc's AST construction API, specifically the requirement to use struct update syntax with the Dummy trait for uninitialized fields.
Changes:
- Updated oxc-related npm packages from v0.112.0/v0.113.0 to v0.114.0 in pnpm-workspace.yaml and pnpm-lock.yaml
- Updated oxc Rust crates from v0.113.0 to v0.114.0 and oxc_resolver from v11.15.0 to v11.17.1 in Cargo.toml and Cargo.lock
- Added
Dummytrait imports and struct update syntax (..Type::dummy(allocator)) to AST construction code in several files to comply with new oxc API requirements - Updated runtime helper version string from 0.113.0 to 0.114.0
- Test snapshots updated to reflect improved code generation: JSX fragments now correctly output
React.Fragment, and dead code elimination is more accurate

This is a regression. It breaks evanw/esbuild@2102e06#diff-06572a96a58dc510037d5efa622f9bec8519bc1beab13c9f251e97e657a9d4edR38

## [1.0.0-rc.5] - 2026-02-18
💡 Smarter `entriesAware` Manual Code Splitting
New `entriesAware` and `entriesAwareMergeThreshold` options for `manualCodeSplitting.groups[]` enable
entry-reachability-based chunk splitting with automatic small chunk merging.
- `entriesAware: true` splits matched modules by entry reachability — modules reached by the same set of entries are grouped together, providing the most precise loading behavior with less over-fetching
- Chunks now get more readable names reflecting their entry associations (e.g. `vendor-entry-a-entry-b.js`) instead of opaque hashes
- `entriesAwareMergeThreshold` sets a byte-size threshold to merge tiny subgroups into the closest sibling with the fewest extra entries, reducing micro-chunk fragmentation while preserving precision
- Recommended to use together with `maxSize`: merge tiny chunks first to reduce request overhead, then cap large chunks to control payload size
```js
manualCodeSplitting: {
groups: [{
name: 'vendor',
test: /node_modules/,
entriesAware: true,
entriesAwareMergeThreshold: 28000, // bytes
}]
}
```
