sobie_curry_daily() creates the daily method described by Sobie and Curry
(2025). It requires matching historical and future daily tas, tasmin,
tasmax, huss, and ps inputs.
The method estimates calendar-neutral change factors with the published
21-day circular window, preserves the baseline CWEC/EPW sequence, and
transforms dry-bulb temperature and surface pressure. The default
"paper_faithful" policy independently transforms dew point and relative
humidity as published. The "harmonized" policy instead applies the
smoothed daily specific-humidity change and derives a physically closed
humidity state from projected temperature and pressure. Other hourly EPW
fields remain unchanged.

Odd circular climatology-window width in days. The
published setting is 21.
Physical execution policy: "paper_faithful" reproduces the
published independent thermodynamic transformations; "harmonized" uses
epwshiftr's specific-humidity closure.
