Initial commit: Matrix Bridge Daemon

Persistent Python daemon connecting Matrix DM room to AiAgent API.

- Config-driven (JSON config file)
- Extensible command system (/new_session, /help)
- Typing indicators while agent processes
- Session auto-naming for identification
- Persistent state across restarts
- Token refresh, retry logic, error handling
- Python stdlib only — no external dependencies
