feat(hooks): add pre-commit quality check hook

- Add pre-bash-commit-quality.js hook script
- Runs quality checks before git commit commands:
  - Lints staged files (ESLint, Pylint, golint)
  - Validates commit message format (conventional commits)
  - Detects console.log/debugger statements
  - Warns about TODO/FIXME without issue references
  - Detects potential hardcoded secrets
- Updates hooks.json with new hook configuration
- Updates README.md with hook documentation

Cross-platform (Windows, macOS, Linux)
