Node.js `Intl.DateTimeFormat` drops month with `calendar: 'iso8601'`

A dateStyle: 'full' formatter configured with calendar: 'iso8601' silently elides the month name from the output. Regression introduced in Node v24.13.0 via an ICU update; reproduces on every release since, including the v26.x current line. Upstream issue #63041 is open with no attached fix PR at recipe-creation time.
