mrkai77/Loop ? reverse-engineered prompt

Build me a macOS window management app like Loop.

I want a small menu bar app that lets me move and resize windows fast with a trigger key and a radial menu, so I can snap the active window to halves, quarters, thirds, center, maximize, or move it to another screen. It should show a live preview before applying the resize, and let me use keyboard shortcuts too, not just the mouse or trackpad.

Please include a stash feature for hiding windows at the screen edge and bringing them back when I hover near the edge or use a shortcut. Also make the look customizable, with colors and simple settings for the menu and preview. The app should feel smooth, elegant, and easy to turn on and off for the parts I want.

If anything is unclear, look up current macOS docs online and make sensible choices for modern Swift and SwiftUI.
