yangluxin613 bc9c1691f5 fix(memory): CJK keyword search + vector search optimization ...

- Add trigram FTS5 table for CJK/mixed-language search with BM25 ranking
- Fix three-step search routing: unicode61 (ASCII) → trigram (CJK/mixed) → LIKE fallback
- Fix _bm25_rank_to_score: abs(rank)/(1+abs(rank)) instead of max(0,rank)
- Fix INSERT OR REPLACE → UPSERT to preserve FTS5 content table rowid stability
- Fix FTS5 JOIN to use rowid instead of id column
- Fix _search_like: single-char CJK match, dynamic scoring, merged CJK+ASCII path
- Add numpy vectorized cosine similarity + BLOB embedding storage (6x smaller)
- Add _decode_embedding backward compat for legacy JSON embeddings
- Add threading.RLock for concurrent write safety
- Add _meta table to avoid trigram backfill re-running on every startup
- Activate EmbeddingCache in MemoryManager for session-level query deduplication
- Add numpy>=1.24 to requirements.txt
- Merge upstream master (embedding package refactor, FTS5 self-healing methods)
