dsh-zh-more: Localizing DSH Plugin Lists and Command Menus into Chinese

`dsh-zh-more` is a DeepSeek Harness plug-in designed to resolve the issue of English display for slash commands and plug-in cards in the official Chinese interface. It offers three translation modes (Chinese only, Chinese-English comparison, and no translation) along with plug-in category tags and source badges. Operating entirely in the browser, it does not affect core functionality. Users can configure it through an installation command to localize English interface elements and improve the experience for Chinese users.
