tutor-done

Close an active tutoring topic. Calculates XP earned from per-concept first-attempt quality, marks the topic complete in state, runs the hybrid feedback flow (thumbs + targeted rotating question with cycles rewards), and logs feedback for later analysis. Invoke when you're done with a topic. Use with no arg to close the currently-active topic, or pass a slug (/tutor-done python-decorators) to close a specific one. Triggers: '/tutor-done', 'I'm done with this topic', 'close out this tutoring session', 'mark this complete'.
