dsh-mermaid-smooth: DeepSeek Harness Renders Mermaid Fenced Blocks by Default

`dsh-mermaid-smooth` is a plugin for the DeepSeek Harness Web UI, maintained by user gitByteFree. It renders Mermaid code fences in conversations as SVG diagrams by default, without relying on external CDNs. The plugin supports smooth zooming, panning, and double-click-to-fit-view, with independent “diagram/text” toggling, state memory, theme following, and security isolation. Users can install it via npm or GitHub; after installation, restarting the service makes it available, providing a smooth chart interaction experience.
