Andy Lee a437f558a3 fix: handle non-daemon threads blocking process exit ...

The root cause was pytest-timeout creating non-daemon threads that
prevented the Python process from exiting, even after all tests completed.

Fixes:
1. Configure pytest-timeout to use 'thread' method instead of default
   - Avoids creating problematic non-daemon threads

2. Add aggressive thread cleanup in conftest.py
   - Convert pytest-timeout threads to daemon threads
   - Force exit with os._exit(0) in CI if non-daemon threads remain

3. Enhanced cleanup in both global_test_cleanup and pytest_sessionfinish
   - Detect and handle stuck threads
   - Clear diagnostics about what's blocking exit

The issue was that even though tests finished in 51 seconds, a
non-daemon thread 'pytest_timeout tests/test_readme_examples.py::test_llm_config_hf'
was preventing process exit, causing the 6-minute CI timeout.

This should finally solve the hanging CI problem.
