dsh-simple-restart: Restart the dsh Web Process from Settings

The `dsh-simple-restart` plugin eliminates the cumbersome requirement to restart the host process when modifying the client bundle in the DeepSeek Harness (DSH) environment. It provides a "Restart dsh web" button in the browser settings interface, preserving original parameters, handling port conflicts, and recording logs. Installation requires the CLI and a specified profile, while usage requires a secondary confirmation. Note systemd monitoring considerations, debugger limitations, and the need to manually clear logs. This tool shifts operational tasks to the interface, enhancing development efficiency.
