dsh-diorama: DSH Character Stage

`dsh-diorama` is a skin plugin for DeepSeek Harness that addresses the issue of limited character visuals in the chat interface. Maintained by ZaVang, it offers dual character portraits, expression stickers, and an editable decoration dashboard. Core features include switching between two sets of skins, custom asset management, drag-and-drop scaling adjustments, and exporting/importing decoration packages in JSON format. The plugin supports local image uploads and automatically saves configurations. After installation, restart the web service to switch skins and edit the layout from the bottom-right corner of the browser, making it suitable for developers to quickly build personalized character scenes.
