dsh-pluginmgmt: DeepSeek Harness Plugin Manager

dsh-pluginmgmt is a DSH plugin manager maintained by zebbkira, designed to simplify plugin management through a web interface. It supports automatic validation and installation by pasting a GitHub link, and provides updating, removal, enabling/disabling, and background auto-update capabilities for installed plugins. After running the install command, users must restart dsh web for the changes to take effect. Plugins do not store credentials and run with the permissions of the current process; users should review the source code and license before installation.
