Fix CI failures: resolve type checker errors and test failures

- Fix type checker errors in reasoning_handler.py: handle Union[str, dict] response types
- Fix type checker error in crew_chat.py: convert final_response to string for dict
- Update test_task_callback_returns_task_output to include completion_metadata field
- Fix integration test attribute access in test_lite_agent_with_xml_extraction
