dsh-restart-autostart: DSH Process Control Plugin

DSH (DeepSeek Harness) has released the `dsh-restart-autostart` plugin, providing an operations management solution for systems that do not natively support process control. Core features include adding a red “Restart” button to any tab of the settings panel, enabling one-click restarts with progress indication; configuring “Launch at system startup” in Settings → General, with autostart support for macOS, Linux, and Windows; and offering a daemon for monitoring host status. Additionally, the plugin supports restarting via a POST API endpoint or script invocation. Note: Linux requires systemd, restarting interrupts active sessions, and upgrading from an older version does not automatically migrate data.
