dsh-motion-ui: Interactive UI and Animations for DeepSeek Harness Web

`dsh-motion-ui` is a plugin for DeepSeek Harness Web, designed to address the challenges of generating complex UIs with models through standardized rendering tools. It reuses the core logic of `dsh-genui`, supporting scene rendering, text layout, native components, canvas drawing, mechanism diagrams, and local computation. It integrates libraries such as ECharts and provides multiple preset styles, with all features running locally to ensure data security. After installation, the Web process must be restarted, and `dsh-generative-ui` should be uninstalled to avoid conflicts. It is primarily suitable for scenarios such as data reports and workflow diagrams.
