Roland Tannous 8fb2fb9e2a Studio: precache RAG reranker on toggle-on, not at app startup
Auto-downloading a 1.1 GB cross-encoder at every studio start is
wrong for users who never use rerank — reranker is opt-in by design.
Move the precache from a startup daemon thread to an explicit
POST /api/rag/reranker/precache endpoint, and have the chat settings
sheet call it the moment the 'Use reranker' switch is flipped on.

  - Backend: drop the startup _precache_reranker thread; add the
    /api/rag/reranker/precache route that calls precache_reranker().
  - Frontend: new precacheRagReranker() in rag-api, wired into the
    Switch's onCheckedChange so the download runs synchronously
    with a loading toast. On success: 'Reranker ready'. On failure:
    error toast + auto-flip the switch back off so the next query
    doesn't trigger another long hang.

First toggle-on pays the 1.1 GB download once; subsequent toggles
hit the HF cache and return ~instantly.
