The recent-observations + forward-forecast bundle is now built without Open-Meteo:
the recent observed window comes from a NASA POWER range (measured, via the range
fetch added for the history flip) and the forward days from MET Norway, merged by
date. Meteostat fills the gusts neither source carries — measured for the observed
days, estimated from wind for the forecast days.
Open-Meteo's forecast API is demoted to the fallback, still gated by its existing
_forecast_cooldown_until rate-limit cooldown; then a stale cache. MET Norway
switched to /compact (same fields, smaller payload) and the bundle TTL relaxed
1h -> 4h. NASA's near-real-time lag leaves a 1-2 day recent-edge gap that grades
as missing, bracketed by history behind and forecast ahead.
Tests updated to the new source order (NASA+MET merge, Open-Meteo fallback, and
the forecast cooldown now gating that fallback); deletion of Open-Meteo is not
done — it stays as the dormant fallback.
