@springbrand/dsh-plugin-marketplace: DSH Visual Plugin Marketplace

`@springbrand/dsh-plugin-marketplace` is a visual plugin marketplace specifically developed for DeepSeek Harness (DSH), designed to address the challenges of managing plugins across multiple profiles in a fragmented and inconvenient manner via the command line. Integrated into the DSH Web settings, this plugin offers a graphical interface for browsing, searching, installing, updating, and removing plugins from a directory. It supports searches by name, author, description, or npm package name, and covers Web, Headless, and other local profiles. Additionally, it features an "Installed" view that displays all installed dependencies, including those from the directory and external sources. Installation requires Node.js version 22.19 or higher, and the plugin is added and activated using the `dsh plugin` command.
