dsh-wsl-launcher: A Windows Desktop Shortcut for Launching DeepSeek Harness Web in WSL

`dsh-wsl-launcher` is a plugin designed to solve the cumbersome process of accessing the DeepSeek Harness Web UI running in WSL from the Windows desktop. It uses desktop shortcuts and command-line tools to enable double-click launching, automatic background execution, and idempotent management. This plugin also supports status checks and service management through the `wsl_launcher` tool within a DSH session, making it suitable for users who need to use DSH in a WSL environment but prefer operating via the Windows desktop.
