Replace the app-local AppLanguage with the shared de.jeanlucmakiola.floret.locale.AppLanguage. The kit version is identical except supportedTags() takes the locales_config XML res id as a parameter (the kit can't reference the app's R), so the call site now passes R.xml.locales_config. Wire the core-locale module into the app. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
