Subject: [PATCH] Run the docs check on pull requests, not only on main.

The deploy workflow already gates on `npm run check`, so a dead link or an
out-of-sync translation cannot reach the site. But it only runs on main, so the
failure lands after the merge: main goes red, and the site quietly keeps serving
the previous build until someone notices and pushes a fix.

Same command, same Node version, on the pull request instead -- where it can
still be acted on.
