- Add precip_1h_in and wx_codes fields to ASOS surface observations - Add IEMRE reanalysis schema for radar-derived hourly precipitation - Add IemreFetchWorker with exponential backoff and idempotency - Integrate IEMRE enqueue into cron weather backfill pipeline - All existing QSOs marked iemre_queued=false for automatic backfill
