* feat(natural): add tropical cyclone tracking from NHC and GDACS
Integrate NHC ArcGIS REST API (15 storm slots across AT/EP/CP basins)
and GDACS TC field extraction to provide real-time tropical cyclone data
with forecast tracks, uncertainty cones, and historical track paths.
- Proto: add optional TC fields (storm_id, wind_kt, pressure_mb, etc.)
plus ForecastPoint, PastTrackPoint, CoordRing messages
- Server/seed: NHC two-pass query (forecast points then detail layers),
GDACS wind/pressure parsing, Saffir-Simpson classification, dedup
strategy (NHC > GDACS > EONET), pressureMb validation (850-1050),
advisory date with Number.isFinite guard
- Globe: dashed red forecast track, per-segment wind-colored past track,
semi-transparent orange forecast cone polygon
- Popup: TC details panel with color-coded category badge, wind/pressure
- Frontend mapper: forward all TC fields, convert CoordRing to number[][][]
* fix(natural): improve GDACS dedup, NHC classification, and TC popup i18n
- GDACS dedup now checks name + geographic proximity instead of name-only
- NHC classification uses stormtype field for subtropical/post-tropical
- TC popup labels use t() for localization instead of hardcoded English
* feat(map): add cyclone-specific deck.gl layers for 2D map
- Storm center ScatterplotLayer with Saffir-Simpson wind coloring
- Past track PathLayer with per-segment wind-speed color ramp
- Forecast track PathLayer with dashed line via PathStyleExtension
- Cone PolygonLayer for forecast uncertainty visualization
- Tooltip and click routing for all new storm layer IDs
* fix(map): remove click routing for synthetic storm track/cone layers
Track and cone layers carry lightweight objects without full NaturalEvent
fields. Clicking them would pass incomplete data to the popup renderer.
Only storm-centers-layer (which holds the full NaturalEvent) routes to
the natEvent popup. Tracks and cones remain tooltip-only.
* fix(map): attach parent NaturalEvent to synthetic storm layers for clicks
Synthetic track/cone objects now carry _event reference to the parent
NaturalEvent. Click handler unwraps _event before passing to popup,
so clicking any storm element opens the full TC popup.
* feat: move EONET/GDACS to server-side with Redis caching and bootstrap hydration
Browser-direct fetches to eonet.gsfc.nasa.gov and gdacs.org caused CORS
errors and had no server-side caching. This moves both to the standard
Vercel edge → cachedFetchJson → Redis → bootstrap hydration pattern.
- Add proto definitions for NaturalService with ListNaturalEvents RPC
- Create server handler merging EONET + GDACS with 30min Redis TTL
- Add Vercel edge function at /api/natural/v1/list-natural-events
- Register naturalEvents in bootstrap SLOW_KEYS for CDN hydration
- Replace browser-direct fetches with RPC client + circuit breaker
- Delete src/services/gdacs.ts (logic moved server-side)
* fix: restore @ts-nocheck on generated files stripped by buf generate
