feat(content): migrate interactiveCopy into six typed collections

Move the six remaining bilingual datasets from app.js:160 into Astro
content collections so GuideSelector has data to drive. Mechanical copy
of 178 strings (160 localized pairs + 18 worker array strings) plus
the non-localized fields (status, path, command, score, icon, title,
number). Source field on commonSkills embedded from skillSources to
match the GuideSelectorData contract; if a URL changes, both this
entry and skillSources/<id>.json must be updated. Status kept on trees
even though GuideSelectorData omits it — index.html renders it.

Did not delete interactiveCopy from app.js: legacy page still consumes
it, and verify.mjs still asserts against it. Did not migrate the
labels (data.labels.*) — those live inside render functions in app.js
and belong to 15d.
