Jonghyeok Park e5d02000c3 perf(hooks): eliminate npx overhead and merge biome invocations
- 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

/**
* PostToolUse Hook: Auto-format JS/TS files after edits
*
* Cross-platform (Windows, macOS, Linux)
*
* Runs after Edit tool use. If the edited file is a JS/TS file,
* auto-detects the project formatter (Biome or Prettier) by looking
* for config files, then formats accordingly.
*
* For Biome, uses `check --write` (format + lint in one pass) to
* avoid a redundant second invocation from quality-gate.js.
*
* Prefers the local node_modules/.bin binary over npx to skip
* package-resolution overhead (~200-500ms savings per invocation).
*
* Fails silently if no formatter is found or installed.
