FlyXingByte/deepseek-harness-macos ? reverse-engineered prompt

Build me a lightweight native macOS app for DeepSeek Harness that feels like a real desktop app, not a browser tab.

I want it to open from the Dock in its own window, with a normal macOS app icon and menu bar, and it should launch the official DeepSeek Harness locally in a clean web view. It should start on Apple silicon, work on macOS 12 and up, and keep the service on 127.0.0.1 so nothing is exposed publicly.

Please make the window feel polished, with theme aware styling, native zoom and font size shortcuts, and no obvious browser chrome or weird web page feel. It should also let me pick a workspace folder, use a sensible default workspace, and show a simple first run flow that guides me to set up models and API keys in the official Harness UI.

If you need to check current docs or behavior, look them up online.
