Wrap the judge prompt and two docstrings past the 120-col convention;
record three implementation rulings in the v0.9 spec (exploration read
outlets, round-based sampling, findings carrying all ratings).
After an exploration session closes, the platform samples up to 3
conversation rounds and runs an independent judge-role review through
the v0.7 ChatClient seam, persisting quality-dimension conclusions
(attitude, professionalism, hallucination) into the session's
judge_review. The review runs as a background task: failures are
recorded without touching session state or the first-hand experience
record, and a missing model config skips silently.
