DeepSeek Harness Plugin: dsh-launch-in-one-click

`dsh-launch-in-one-click` is a DSH plugin designed for Windows environments, intended to address port conflicts and environment-checking issues when frequently launching Harness instances. It enables one-click startup by generating self-contained `.bat` launchers on the desktop, with built-in environment pre-checks, port probing, and conflict-prevention mechanisms. The tool supports management via slash commands or tool commands. The generated launchers can run independently and remain usable after the plugin is uninstalled, while atomic operations and logging help ensure a stable and secure startup process.
