feat(system-builder): the WORDS page (4b1b)

[over2take]

components/WordsPage.tsx, from the approved mockup builder-words-features (2026-10-06): the app's terms in their groups, one / many / short boxes with the app's word as placeholder (blank = the app's, nothing stored), READS AS, RESET per term, and terms whose part is off greyed with where to turn it on. Every change goes through the builder's edit (autosaved). BuilderScreen shows it on WORDS.
