Generate Quiz

When invoked:

1. Accept a topic, source scope, difficulty, and target number of questions.
2. Retrieve top-k chunks from the Qdrant vector store.
3. Generate MCQ, short-answer, or true/false questions via the local LLM.
4. For each question, include:
   • answer / answer_index
   • rationale (one sentence)
   • supporting_chunk_ids
   • confidence_flag (ok | low | rejected)
5. Validate grounding: reject hallucinated questions.
6. Save outputs under outputs/ using a slug derived from the topic (<sanitized_prefix>_<8hex>). Use ls outputs/quizzes/ to find the exact filename, e.g.:
   • outputs/quizzes/gpu_monitoring_3f8a1c2e.{json,md,csv}
   • outputs/answer_keys/gpu_monitoring_3f8a1c2e_key.md
   • outputs/rationales/gpu_monitoring_3f8a1c2e_rationales.md
7. Refuse to generate unsupported answers if evidence is insufficient.
