dsh-quick-window-launcher: Turning DeepSeek Harness Into a Standalone Application Window

This plugin opens DeepSeek Harness (DSH) in a standalone Chromium app window via a desktop shortcut, delivering a native app-like experience. It includes sidebar power controls, the `open_web` tool, and automatic version checking. Core features include desktop shortcut generation (using `--app` mode by default), watchdog-based process heartbeat self-healing and graceful restart, multi-signal liveness detection to avoid conflicts, and a pure Node.js helper script to ensure antivirus compatibility. After installation, Harness must be restarted, and options such as shortcut generation can be overridden through configuration.
