  1. feat: enable MMR diversity for hybrid search 

    MMR (Maximal Marginal Relevance) was artificially blocked for hybrid
search in QQL, even though the Qdrant SDK supports it: Prefetch.query
accepts NearestQuery, which carries an MMR field.

- Remove the hybrid guard from _validate_search_mmr_usage
- Wire _build_dense_query() into the dense prefetch of both flat and
  GROUP BY hybrid paths, so MMR params produce a NearestQuery(mmr=...)
  instead of a raw vector
- Keep the sparse-only and recommend guards (MMR is a dense-space
  concept and RecommendInput has no MMR field in the Qdrant API)
- Replace test_hybrid_search_with_mmr_raises with a new test that
  asserts NearestQuery + MMR is passed in the dense prefetch
