fix: clean up stale and obsolete tests

- test_deep_agent: update patch target get_llm -> get_agent_llm (8 tests)
- test_device_ws: remove 5 tests for deleted agent_data_queue API
- test_schemas_v3: remove agent_run/agent_data/agent_complete from v2 compat list
- Delete test_agent_runner.py (superseded by test_agent_runner_v2.py)
- Delete test_agent_setup.py (superseded by test_journey_v2.py)
- Delete test_classify_file.py (_classify_file removed in v2 rewrite)
