Refactor tests and enhance coverage for conflict resolution and edge cases

Browse Source 
- Removed outdated tests for missing lines in core.py.
- Added comprehensive tests for conflict resolution functionality, including various resolution strategies and edge cases.
- Improved error handling tests for archive creation and extraction processes.
- Enhanced unit tests for basic functionality and convenience functions with pytest markers.
- Introduced tests for unique filename generation and conflict handling scenarios.
- Added edge case tests for archive extraction and error conditions to improve overall test coverage.
