Notification Rule Scheduler

Vercel Cron infrastructure that triggers the Notification Rule Engine on a configured schedule. Manages the cron expression, passes the correct evaluation time window to each run, implements a concurrency guard to prevent overlapping executions, and surfaces scheduler errors for alerting when consecutive runs fail.
