Translating an English-default MII KDS module IG into German

Experimental. This skill has not been verified against a real task since its last change. Verify its output before relying on it.

Produces the German translation supplements of a module IG and puts them exactly where the IG Publisher looks for them. English is the default language; German is the translation.

Preconditions

1. Locate the IG. From the working directory, expect input/pagecontent/ together with a sushi-config.yaml or an ig.ini. scripts/ig-translate.sh checks this itself and exits 2 with a message if the directory is not an IG project — it deliberately does not report "nothing to translate", which is what a silent failure here looks like.
