Pull Request Overview

This PR reorganizes the test suite by splitting tests from a monolithic file into separate, focused files based on functionality. It adds comprehensive documentation and type annotations to all test functions, and successfully migrates CLI tests from bash scripts to Python for better maintainability and coverage tracking.

Key changes:

• Split test_major_functionality.py into 6 focused test modules (test_match.py, test_server_local.py, test_config.py, test_download.py, test_cli.py, test_api_public.py)
• Migrated bash-based CLI tests to Python with parametrized tests
• Modified __main__.py to support programmatic testing by accepting argv parameter and refactoring stdin handling
• Added coverage badge generation to build process and README
