Refactor documentation and remove CI/CD integration references

- Updated README.md to clarify local testing instructions and added error handling for low scores.
- Removed CI/CD configuration details from CONFIGURATION_GUIDE.md and other documentation files.
- Cleaned up MODULES.md by deleting references to the now-removed github_actions.py.
- Streamlined TEST_SCENARIOS.md and USAGE_GUIDE.md by eliminating CI/CD related sections.
- Adjusted CLI command help text in main.py for clarity on minimum score checks.
