Build me a lightweight Windows app that turns my old phone into a Stream Deck for my PC.

I want one small Go executable that runs on my Windows 10 or 11 machine, stays on my local Wi Fi, and opens a simple phone friendly web interface in Safari or any browser. The phone should pair to the PC by scanning a QR code, then show a dashboard with media controls, a few customizable tiles to launch games or apps, per app volume controls, mic mute, brightness, a trackpad, and live CPU and GPU stats. It should also have a watch mode for the couch with play, pause, skip, volume, brightness, and power options.

I need a tray based desktop dashboard on the PC where I can add phones, manage tiles and games, and see connected devices. Make it feel fast and simple, with no cloud account, no sign in, and a small memory footprint. If you need to, look up current docs for any browser or Windows details.
