Vite plugin that runs TypeScript type checker on a separate process.

* Bucket a flat diagnostic list by file and write per-file diagnostics
* to the manager. Every file in `scannedFiles` is written (empty list
* clears stale diagnostics). Files not in `scannedFiles` are untouched.
*
* Paths are normalized via `sources.ts#normalizePath(root)` on both sides
* before keying to defend against checker normalizers that differ in
* casing, separators, or unresolved `.` segments.
