vcspull(feat[operations]): Implement repository operations API and VCS adapters

why: Provide core functionality for repository synchronization and discovery, completing essential parts of the project roadmap.

what:
- Added sync_repositories function with parallel processing support
- Implemented detect_repositories function with recursive directory scanning
- Created adapter classes for Git, Mercurial, and Subversion handlers
- Enhanced CLI commands with rich output formatting and JSON support
- Added save_config function to complete Configuration API
- Fixed VCS module import errors and type annotations
- Improved error handling with consistent error message formatting
