DeepSeek Harness Plugin Collection: Sandbox Permission Handling and Path Viewer

`@MarvekG/dsh-plugins` is a plugin collection for the DeepSeek Harness ecosystem, designed to address two core issues in agent development: handling redundant sandbox permission errors and fixing file path click failures in the web interface. The plugin provides sandbox permission cleanup by removing redundant fields to avoid conflicts, and intercepts native file-open requests to display files or directories in the browser via the `/view` route instead. It includes two independent entry points, supports syntax highlighting, and can be installed from GitHub or a local path. To upgrade, uninstall the existing package first and then install the new one.
