✨ Add type hints and improve compatibility with Python 3.11+

Add proper type annotations throughout the codebase for Python 3.11+

- Implement PEP 604 style type hints (T | None) where appropriate
- Add comprehensive typing to CLI functions for better IDE support
- Fix potential edge cases in gradient text rendering
- Add missing types in client and effect_cycler example
- Replace class attribute access with safer optional checks
- Include types-requests for better type checking compatibility
- Fix version in __init__.py to match current release
- Add proper type annotations in tests with cast() for JSON data
