Complete LOOP-WP-0002: event-driven quality escalation smoke + daily backup cadence

ACTIVITY-WP-0011 event-payload resolver unblocked the reactive path. Live NATS
smoke confirmed tasks_spawned=1 for low-success-rate-review. Promoted sweep from
hourly bootstrap to daily backup (disabled); cadence.yml now in stabilize phase.
