DeepSeek Harness Web Control and Pet Supply Plugin

The `w2831120407/dsh-ctl` plugin for DeepSeek Harness (DSH) integrates system control and pet interaction features into the Web settings panel. It allows users to restart or stop the dsh process with a single click from the web interface and to add dried small fish for the built-in pet “Whale Girl” without terminal operations. Installation requires linking the local directory and restarting the service; when using it, pay attention to process matching and operation confirmation.
