- Text: Default human-readable format
- Ensure consistent schema across formats
- Add output validation
Version Information
- Add version flag handler
- Display:
- Globstar version
- Git commit hash
- Go version used for build
Acceptance Criteria
- All flags work as specified when used individually
- Flags work correctly in combination
- Meaningful error messages for invalid usage
- Documentation updated to reflect new options
- Tests added for new functionality
- CI pipeline updated to test new options
