Agent Skills: fleet-stop

Gracefully wind down a running fleet of /loop /auto sessions — writes an already-passed deadline so every session finishes its in-flight issue, then stops picking new work. Nothing is killed. Quota rationing is the primary use. Use when the user says 'fleet stop', 'stop the fleet', 'wind down the fleet', 'end the fleet early', 'discontinue the fleet', or invokes /fleet-stop.
