Add custom git pre-commit hook for ruff

[johnnymo87]

Summary

• Added a custom git pre-commit hook that runs ruff code quality checks
• Created setup-git-hooks.sh script for easy installation
• Updated documentation with setup instructions
• Configured ruff to handle type-checking import rules appropriately

What this adds

• setup-git-hooks.sh: Installation script for the git hook
• Pre-commit hook: Runs ruff check and ruff format --check automatically
• README updates: Clear instructions for optional git hook setup
• Ruff config: Added TC002 to ignore list for type-checking imports

How it works

1. Run ./setup-git-hooks.sh to install the hook
2. Hook automatically runs on every git commit
3. Checks only main package directories (excludes test/demo files)
4. Provides clear error messages and fix suggestions
5. Can be bypassed with git commit --no-verify when needed

Benefits

• ⚡ Fast feedback: Catch issues before they reach CI/CD
• 🔧 Simple: No additional tool dependencies beyond uv + ruff
• 🎯 Focused: Only checks main package code, not test files
• 💡 Helpful: Clear error messages with fix suggestions
• 🚀 Optional: Easy to install/skip as needed

Test plan

• Hook installation script works correctly
• Hook runs ruff checks on commit
• Hook provides clear error messages for failures
• Hook can be bypassed with --no-verify
• Documentation is clear and complete
