feat: enhance Python tree-sitter parser with advanced language structures

This commit significantly enhances the Python tree-sitter parser to support a comprehensive range of Python language constructs, enabling more accurate and detailed code analysis.

Key improvements:
- Added support for method definitions (instance, class, and static methods)
- Added support for decorators on functions and classes
- Added support for module-level variables and constants
- Added support for async functions and methods
- Added support for property getters/setters
- Added support for type annotations in various contexts
- Added support for dataclasses
- Added support for nested functions and classes
- Added support for generator functions
- Added support for list/dict/set comprehensions
- Added support for lambda functions
- Added support for abstract base classes and methods

The parser now handles Python's rich feature set more comprehensively, including special Python patterns like decorators, type annotations, and various comprehension types. This enables better code navigation, understanding, and analysis for Python codebases.
