964a3f6075 feat: scheduled reminders + less aggressive article summary 
Add scheduled messages/reminders system:
- New scheduled_messages table in memory-service with CRUD endpoints
- schedule_message, list_reminders, cancel_reminder tools for the bot
- Background scheduler loop (30s) sends due reminders automatically
- Supports one-time, daily, weekly, weekdays, monthly repeat patterns

Make article URL handling non-blocking:
- Show 3 options (discuss, text summary, audio) instead of forcing audio wizard
- Default to passing article context to AI if user just keeps chatting
- New AWAITING_LANGUAGE state for cleaner audio flow FSM

1c8d45c31b fix: harden Matrix ecosystem — pool recovery, parallel queries, voice persistence 
- Memory service: asyncpg pool auto-reconnect on connection loss, IVFFlat lists 10→100
- Bot: parallel RAG/memory/chunk queries (asyncio.gather), parallel tool execution
- Bot: skip memory extraction for trivial messages (<20 chars, no personal facts)
- Bot: persist voice call transcripts as searchable conversation chunks
- RAG: JSON parse safety in AI metadata, embedding_status tracking, fetch timeouts
- Drive sync: token refresh mutex to prevent race conditions, fetch timeouts

36c7e36456 security: enforce per-user data isolation in memory service 
- Make user_id required on all request models with field validators
- Always include user_id in WHERE clause for chunk queries (prevents cross-user data leak)
- Add bearer token auth on all endpoints except /health
- Add composite index on (user_id, room_id) for conversation_chunks
- Bot: guard query_chunks with sender check, pass room_id, send auth token
- Docker: pass MEMORY_SERVICE_TOKEN to both bot and memory-service

fb54ac2bea feat(MAT-13): Add conversation chunk RAG for Matrix chat history 
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

4cd7a0262e feat: Replace JSON memory with pgvector semantic search (MAT-11) 
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.
