"""Cross-tick cooldown for notification-triggered spawns.
Escalation/approval/audit/a2a dispatchers carry no task_id, so neither the
readiness gate nor the PM respawn breaker sees them — the cooldown is the
loop-breaker that stops an unacknowledged notification from respawning its
recipient every dispatch tick.
