Subject: [PATCH] chore: migrate to lefthook for git hooks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace custom bash pre-commit hook with lefthook for:
- Parallel execution of ruff + pytest
- Quieter output (pytest -q instead of -v)
- Version-controlled config (lefthook.yml)
- Smart skipping when no .py files staged
