English is now the default language. Added src/i18n.ts (t() helper + dictionary) covering all UI strings across App, Updater and ModelViewer, plus a language selector in Settings for English, Русский, Deutsch, Français, Español (persisted in localStorage). Backend error strings translated to English. Also removed the purple highlight on the resize handles (cursor-only). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
