dsh-soup: DeepSeek Harness UI Enhancement

dsh-soup is a UI enhancement plugin specifically designed for DeepSeek Harness (DSH), aimed at improving its file management and interaction experience. It provides four core features: a JupyterLab-style file tree on the right side, supporting file upload, download, preview, and renaming; a new “Preview” tab in the conversation area, supporting various formats such as Markdown, PDF, and code, along with direct editing; the truncation of the GoalBar changed to a multi-line display; and the real-time token generation rate displayed in the conversation header. The plugin is easy to install and requires restarting DSH to take effect, making it suitable for users who need efficient file management and monitoring of model inference speed.
