Add a 2,647-row zh-Hant catalog (1,975 UI strings, 641 command labels, 31 menu wordings), locale mapping for zh-TW/zh-HK/zh-MO/zh-Hant, and a Noto Sans CJK TC-first fallback. The catalog is marked draft pending native review; the web picker stays hidden because craft-fonts currently ships only the Simplified CJK face.
