Environment

Daily marine forecast (up to 8 days with past_days lookback)

Daily marine forecast up to 8 days: wave heights, direction, period, swell, sea temperature. Optional variables lets clients opt into the widened Open-Meteo daily palette (peak periods, wind/swell period maxima). Optional past_days enables retrospective lookback up to 92 days. Omitting both keeps the legacy response shape unchanged.
