Add Windows Player support and related files

- New windows/ directory with build scripts, specs, and configuration
- Windows-specific requirements (requirements_win.txt)
- Launch and runtime scripts for Windows (run_win.py, launch_player.bat)
- PyInstaller build configuration (build.spec)
- Updated .gitignore to exclude windows/venv312/
- Updated config and source files for Windows compatibility
- Moved working_files to proper directory
