allextraszza1488/hypr-cardboard ? reverse-engineered prompt

Build me a small Linux tool for Hyprland that lets me play a PC game inside a Google Cardboard headset through Sunshine and Moonlight.

I want it to turn the game view into a side by side split for left and right eye, but only when the game is focused and truly fullscreen. When I alt tab away or stop streaming, it should go back to normal automatically. Please make it work as a simple installable script that copies the needed helper into my local bin, installs the shader file in my local share folder, and adds a new Sunshine app entry without overwriting my other apps.

It should also have a manual command mode so I can turn the split on, off, toggle it, or run an auto mode for a specific window class. If you need to check the latest Hyprland or Sunshine details, look up the current docs online. Keep it lightweight, user friendly, and easy to remove later.
