AIS Agent Flight Recorder — dead-man alerts & resume for AI agents

Agent Flight Recorder — FREE (1 monitor per alert target) / Gateway key (20 monitors + stored capsules + fleet view). Register an agent or scheduled job to be watched: you get a monitor_id + secret; the agent then calls heartbeat every period_minutes. If heartbeats stop for period + grace, the alert target (Discord/HTTPS webhook and/or email) is notified with the last state capsule and a resume link.

Agent Flight Recorder — "still alive" ping for a registered monitor. Include capsule (any JSON ≤32KB: current step, done, next, ids) so a dead-man alert can carry resume state (stored on the key tier). status:"fail" reports a failure immediately.
