Add semantic search over past conversations alongside existing memory facts.
New conversation_chunks table stores user-assistant exchanges with LLM-generated
summaries embedded for retrieval. Bot queries chunks on each message and injects
relevant past conversations into the system prompt. New exchanges are indexed
automatically after each bot response.
Memory-service: /chunks/store, /chunks/query, /chunks/bulk-store endpoints
Bot: chunk query + formatting, live indexing via asyncio.gather with memory extraction

Add memory-service (FastAPI + pgvector) for semantic memory storage.
Bot now queries relevant memories per conversation instead of dumping all 50.
Includes migration script for existing JSON files.
