Add two new tables for cross-chat memory feature: - memory_facts: stores explicit user-provided facts (user_id, content, created_at) - conversation_summaries: stores conversation summaries with vector embeddings for similarity search This migration prepares the database schema for Task 2-7 of the cross-chat memory feature plan. No indexes yet (sequential scan sufficient for expected data volume).
