Add QA testing step to task completion protocol

Before git commit, agents must now run pytest tests/ -v --tb=short to verify
their changes don't break existing functionality. The protocol now:

1. Document Changes
2. Run Tests (NEW - required step)
3. Git Commit
4. Knowledge Graph

This ensures code quality and prevents regressions.
