Agent IPC (cryo-agent)

These commands are used by the AI agent to communicate with the daemon. They send JSON messages over a Unix domain socket.

cryo-agent hibernate --summary "..."   # End session (more work to do)
cryo-agent hibernate --complete        # End session (plan done)
cryo-agent todo add "text" --at <TIME> # Schedule next wake via TODO
cryo-agent note "text"                 # Leave a note for next session
cryo-agent send "message"             # Send message to human (writes to outbox)
cryo-agent receive                     # Read inbox messages from human
cryo-agent time "+30 minutes"          # Compute a future timestamp
cryo-agent alert <action> <target> "msg"  # Set dead-man switch

GitHub Sync (cryo-gh)
