Release 2026.7.8

Add - localized store listing (EN/DE)

• The extension name, store summary, and toolbar tooltip are now localized in
  English and German via _locales and manifest __MSG__ placeholders, with
  en as the default locale. This lets the Chrome Web Store serve the listing
  (name + short description) in the user's language and unlocks per-language
  detailed descriptions in the dashboard. The runtime UI keeps its own bundled
  catalog (i18n.js); the two are independent. The toolbar tooltip now follows
  the browser language via chrome.i18n.getMessage. Both the local
  npm run build and the release zips include _locales.
