Redesign integration test architecture to eliminate async/sync deadlock: - Run SimulationServer in dedicated background thread with own event loop - Rewrite TempCo tests as fully synchronous (no @pytest.mark.asyncio) - Add ServerThread fixture in tests/integration/conftest.py - Fix Unicode encoding errors (replace deg, mu, +/- with ASCII) - Optimize temperature points for faster settling (23C, 25C, 27C) All 3 TempCo integration tests now passing in ~5 minutes total. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
