 * a user-facing surface. This statically scans every WP i18n call in
 * app/Toolbar + app/QuickEdit and fails if any translatable string
 * contains "Extendify" — catching reintroduction anywhere in those
 * features, not just the one aria-label we neutralized.
 *
 * Pairs with .github/translations/scan-redflags.py, which guards the
 * translated side (no "Extendify" in any locale's msgstr).
