Add activity_core/schedule_health: a pure evaluate_schedule_health() verdict (built on Temporal's num_actions_missed_catchup_window plus a staleness check), an async check_schedule_health() reader, and post_missed_fire_alert() that emits a schedule_miss State Hub progress event. Makes a missed fire visible even under misfire_policy=skip, where Temporal drops it by design. Unit tests for the verdict logic. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
