Users can send /remote-control from the main group in any channel to
spawn a detached `claude remote-control` process on the host. The
session URL is sent back through the channel. /remote-control-end
kills the session.
Key design decisions:
- One global session at a time, restricted to main group only
- Process is fully detached (stdout/stderr to files, not pipes) so it
survives NanoClaw restarts
- PID + URL persisted to data/remote-control.json; restored on startup
- Commands intercepted in onMessage before DB storage
