admin 6271f3726e Improve VectorDB search: multi-query, topic boosting, wider recall ...

- Generate multiple query variants (entities, topic words, combined)
- Search with top_k=30 per sub-query for wider recall
- Boost results matching multiple topic words for relevance
- Deduplicate and merge across all sub-queries
- Return top 15 results (up from 10) for richer RAG context
