Test suite for Issue #57: Try to be more efficient automatically calling the tests

This test module validates test runner efficiency improvements including:
- Clean test discovery (excluding workspace directories)
- Intelligent test selection based on changes
- Cache management and cleanup
- Fast feedback for TDD workflows
- Enhanced make targets

Created for Issue #57: https://gitea.coulomb.social/coulomb/markitect_project/issues/57
