Graham McIntire d880201713 Cache propagation scores in ETS, broadcast across cluster
- Add ScoreCache GenServer with node-local ETS table keyed by
  {band, valid_time}, subscribed to "propagation:cache" PubSub topic so
  every pod stays in sync with a single hourly compute
- scores_at/3 checks cache first, falls back to DB and populates on miss
- PropagationGridWorker warms and broadcasts the cache for each band
  after every forecast hour upsert; prunes >2h old entries
- Replace per-pixel string-keyed Map with flat Int8Array over the CONUS
  grid in propagation_map_hook.ts to eliminate allocations in the tile
  rasterization hot loop (interpolateScore / propagationReach)
