fix: add Windows support with entry_points and os.replace

- Replace os.rename() with os.replace() for atomic file operations
  on Windows (os.rename fails if destination exists on Windows)
- Add entry_points console_scripts for proper .exe generation on Windows
- Create github_backup/cli.py with main() entry point
- Add github_backup/__main__.py for python -m github_backup support
- Keep bin/github-backup as thin wrapper for backwards compatibility

Closes #112
