## Summary

- Adds `modules: string[]` and `chunk_ids: number[]` to `PackageInfo`, mapping each package to its generated chunk module IDs and the matching `ChunkGraphReady` chunk IDs.
- Both arrays are empty for unused (fully tree-shaken) packages.

Stacked on #9423. Part of #9399.

## Summary

- Adds `is_used` to `PackageInfo` and collects packages from all resolved normal modules, so fully tree-shaken packages still surface as unused entries instead of disappearing from the report.
- `is_used` is true when at least one resolved module for the package is included after tree shaking, false otherwise.

Stacked on rolldown#9422. Part of rolldown#9399.

- Adds `modules: string[]` and `chunk_ids: number[]` to `PackageInfo`, mapping each package to its generated chunk module IDs and the matching `ChunkGraphReady` chunk IDs.
- Both arrays are empty for unused (fully tree-shaken) packages.
