feat: Migrate installer from Bash to Python with improved cross-platform support

This PR introduces a complete rewrite of the installation system from Bash to Python, providing better cross-platform compatibility and enhanced functionality.

Key Changes:
- **Python-based installer**: Replaced install.sh with install.py for better error handling and cross-platform support
- **Modular architecture**: Split installer into focused modules (dependencies, devcontainer, downloads, env_setup, files, migration, shell_config, ui, utils)
- **Bash 3.2 compatibility**: Updated file_checker_python.sh to work with macOS default bash (3.2) by replacing associative arrays with simple variables
- **Improved user experience**: Better progress tracking, error messages, and interactive prompts
- **Updated documentation**: Modified README.md to reflect the new Python-based installation command

The new installer maintains all existing functionality while providing a more robust and maintainable codebase.
