1. WZDx work zones: replace per-event broadcasting with a once-a-day
per-region count summary. Coalesce the upstream per-direction /
per-schedule-day fan-out into one row per physical zone
(road + lat3 + lon3 + sub_type); work zones are stored in
traffic_events but no longer per-event broadcast, while 511 crash /
closure / hazard incidents still broadcast live. A WZDxSummaryScheduler
emits one count line per coverage region once a day (default 07:00
America/Boise), routed via the region_routes 'roads' cells; work-zone
details are DM-queryable (build_work_zones_detail). New config:
wzdx.summary_enabled / summary_time / summary_tz.
2. FIRMS cold-start is now restart-safe: gate the silent-seed on the
persisted firms_pixels baseline being empty (first-ever run) instead of
an in-memory per-boot flag, so a restart no longer silently absorbs a
genuinely-new hotspot cluster.
