Auto-exit server after 30 minutes idle, add liveness check to skill

Browse Source 
Server tracks activity (HTTP requests, WebSocket messages, file
changes) and exits after 30 minutes of inactivity. On exit, deletes
.server-info and writes .server-stopped with reason. Visual companion
guide now instructs agents to check .server-info before each screen
push and restart if needed. Works on all harnesses, not just CC.
