* feat(client): add Traditional Chinese (zh-TW) language support Update language switcher and i18n configuration to include Traditional Chinese. Modify locale resolution to prioritize exact matches (zh-TW) over base codes (zh), ensuring accurate browser language detection. Add complete translation set. Co-authored-by: Copilot <copilot@github.com> * feat(i18n): improve BCP-47 locale resolution and browser languages Refactor resolveLocale to use a normalize helper that correctly maps BCP-47 tags to supported locale keys, properly distinguishing Traditional vs Simplified Chinese variants. Additionally, iterate over navigator.languages instead of relying solely on navigator.language to respect the browser's full language preference list.
