structure-check: gate counts code lines, docs and comments in English

Gate ignores blank and full-line comment lines so the 250-line limit
measures code bulk, not documentation weight; docs/README.md synced.
Translate code comments to English in classfile, core config, namegen,
rename assign, constants forms. Expand Plausible word bank with
client-ecosystem terms (Module, Setting, Mixin, ...). cargo fmt clean,
check.sh green.
