- Use local node_modules/.bin/biome binary instead of npx (~200-500ms savings)
- Change post-edit-format from `biome format --write` to `biome check --write`
(format + lint in one pass)
- Skip redundant biome check in quality-gate for JS/TS files already
handled by post-edit-format
- Fix quality-gate to use findProjectRoot instead of process.cwd()
- Export run() function from both hooks for direct invocation
- Update tests to match shared resolve-formatter module usage
