feat(cli): add initial repository management commands

- Introduce CLI using Typer for repository management
- Add commands for archiving, cleaning, moving, reviewing, and status
- Implement configuration loading and default structure setup
- Include utilities for Git status checks and directory size calculation
- Lay groundwork for extensible repository operations
