- Convert List[str] to list[str], Dict[str, Any] to dict[str, Any], etc.
- Use ruff --unsafe-fixes to automatically apply all type annotation updates
- Remove deprecated typing imports (List, Dict, Tuple) where no longer needed
- Keep Optional[str] syntax (union operator | not supported in Python 3.9)
Now all type annotations are Python 3.9 compatible with modern builtin generics.
