fix(ci): address Copilot review feedback and skip tests for CI-only changes

- Check Copilot review existence before checking comments (fixes race condition)
- Only trigger Unity tests for unity-tests.yml and pr-tests.yml changes
- Other CI workflow changes (auto-approve, etc.) no longer run Unity tests
