AIS Agent Flight Recorder

**A dead-man switch for AI agents and cron jobs.** Your agent calls `heartbeat` on a schedule (optionally with a JSON state capsule); if it goes silent past its grace period, your Discord/webhook/email gets the alert with the last capsule and a resume link — so you (or a fresh agent) can continue from the step it died on. `register_monitor` + `heartbeat` are free (1 monitor per alert target, alerts only). A Gateway key (scope `recorder` or a campus pass — https://aislabs.ai/gateway) unlocks 20 monitors, stored capsules, `fetch_capsule`, and `fleet_status`. HTTP twins at https://api.aislabs.ai/v1/recorder (one-line curl heartbeats for cron). Part of the AIS campus: the front desk server `aislabs/ais-gateway` lists every building.
