- Refactor tests in test_workflow.py, test_memory.py, and test_signal_handling.py
to use assertions instead of returning booleans (pytest strict mode requires None)
- Fix test_batch_orchestrator.py to mock file finding to avoid filesystem scans
- Add 'integration' pytest marker to both root pyproject.toml and pkg/hanzo/pytest.ini
- Account for system memories in memory manager tests
