dsh-server-admin: DSH Server Administration Panel

`dsh-server-admin` is a Web management plugin for DeepSeek Harness (DSH), maintained by sunnywangzi. It provides visualized server operations and maintenance capabilities, with core features including process monitoring, online restart/stop, one-click systemd keep-alive, online plugin installation, session management, and a root-privileged command terminal. After installation, users can perform configuration and operations through the Web interface instead of SSH. The notes emphasize paying attention to API security, permission scopes, and network exposure risks.
