Subject: [PATCH] chore: add pre-commit hook for protected branch validation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a git hook that:
- Blocks commits to main/dev if validation fails
- Runs `make validate` for backend changes
- Runs `npm run validate` for frontend changes
- Skips validation for feature branches (can run manually)

To enable: git config core.hooksPath .githooks
