wiyi/dsh-web-service-manager: Panel-Based Management for DSH Web Services

`wiyi/dsh-web-service-manager` is a web management plugin for DeepSeek Harness (DSH), designed to replace terminal-based operations. Once installed, users can view service status, version, PID, and other information at a glance in the settings panel. Core features include service restart (ensuring graceful cleanup), stop (closes the GUI window), version checking, and one-click updates. A manual browser refresh is required after restarting or updating. Installing it means running third-party code; be sure to review the source code before deploying to critical environments.
