M33 lab, conversational RAG

A follow-up needs its subject back.

Six three-turn Larkspur Cloud support chats over the twelve handbook chunks from the M10 lab, ranked with the same real TF-IDF. Choose what the retriever receives on turns two and three, then read the hit rate.

    Twelve follow-ups: turns two and three of six chats. This is the comparison the M33 lab brief asks for, on a small scale.
