Format an ICU-subset message with params, using language for plural category
selection and # number rendering (see the module doc for the exact subset).
This is the single formatting path behind ITranslator.t/lookup — pack
messages format with the active language, the English call-site fallback with 'en'.
Plain {name} messages behave exactly like interpolate.
