- Enabled Biome VCS settings and expanded fix scripts with new `fix:all` and `fix:tools:all` commands.
- Updated `fix:ts` and `fix:tools` to separate changed-only checks from full-run formatting and generation tasks.
- Simplified edit-benchmark variant parsing by removing hardcoded validation logic, and removed deprecated flags from `run-rs-task.ts`.
- Replaced the standalone chunk and vim benchmark scripts with a unified `scripts/edit-benchmark.py` entrypoint.
- Added `--variant` and `PI_EDIT_VARIANT` handling with validation for supported edit modes.
- Generated benchmark specs dynamically per variant with mode-specific prompts and retry instructions.
