feat(i18n): add zh-TW Traditional Chinese locale with Taiwan terminology (#248)

- Add zh-TW locale with Taiwan-specific terms (檔案, 終端機, 記憶體, 市集, 設定, 儲存, 搜尋, 載入中 etc.)
- Update getLocale() to match full navigator.language before splitting, ensuring zh-TW users are not routed to Simplified Chinese
- Rename zh label to 中文（简体）for clarity
