## Summary by CodeRabbit

- **Refactor**
- Streamlined Git operations to consistently use a new file system-based
handler, replacing previous executor-based implementations across the
application and tests.
- Updated method and constructor signatures to reflect new dependencies
and abstractions for artifact handling and repository management.
- Improved metadata handling and resource mapping for Git-related
workflows.

- **Tests**
- Updated test suites and helpers to align with the new Git handler and
artifact helper resolver, ensuring continued reliability and coverage.

- **Documentation**
  - Corrected minor spelling errors in documentation comments.
