fix: Replace remaining deprecated typing imports with built-in types

- Replace List[...] with list[...] in crew.py method signatures
- Replace Dict[str, Any] with dict[str, Any] in crew.py and task.py
- Fix all undefined name errors from deprecated typing imports
- Maintain backward compatibility while modernizing type hints
