test(chat): T-commit — inline display (OUTPUT_NODE + dict return)

5 failing unit tests:
- test_chat_is_output_node
- test_chat_returns_ui_result_dict
- test_chat_ui_contains_response_text
- test_chat_result_is_3_tuple
- test_wired_model_name_overrides_combo (updated to unpack from ["result"])

Integration tests updated to unpack from ["result"] for API consistency.
