_llm.py 295 -> 217, clearing the last code_tutor source violation; only
its seven test modules remain over the cap.
The seam falls between the two backends because each pins a different
plain import: test_llm.py patches requests.post on _llm for
OllamaBackend and anthropic.Anthropic for ClaudeBackend. _llm keeps its
own anthropic import - complete_with_fallback still catches APIError -
so the four anthropic patch strings were split per test rather than
moved wholesale.
Pass count is 217 before and after.
