Build me a macOS window manager app that automatically tiles and arranges windows in a clean, keyboard driven way, kind of like xmonad.

I want it to run in the menu bar or as a background app, ask for Accessibility permission, and then keep windows neatly organized without me dragging them around. It should support common tiling layouts like tall, wide, columns, fullscreen, and floating, with shortcuts to switch layouts, move focus between windows, resize the main area, and send windows to other spaces or screens.

Please make it feel polished and configurable, so I can turn tiling on or off, choose which layouts are available, and edit the shortcut setup with a simple config file. If needed, look up the current macOS docs online for any permission or space handling details. Make it easy to install and test, and include a basic preferences screen or status view so people can understand what it is doing.
