Add type annotations and docstrings across modules

- Introduced type annotations for functions, methods, and class variables
- Added docstrings to improve code clarity and maintainability
- Improved consistency in function signatures and replaced ambiguous types with specific ones
- Updated `setup.py` and key modules with better descriptions and format adjustments
