Matrix Bridge Daemon — connects Lucy's Matrix DM to the local agent API.

Polling loop that listens for new messages in a Matrix room, forwards them
to the AI agent framework, and sends responses back.

Usage:
    python3 main.py                          # Normal mode
    python3 main.py --config path/to.json    # Custom config
    python3 main.py --debug                  # Verbose logging
