bhavesh164/mouseless ? reverse-engineered prompt

Build me a macOS app that lets me control the mouse with just the keyboard.

I want a status bar app called Mouseless that can open a full screen overlay grid with a hotkey, let me keep narrowing down a target cell with letters, then click, double click, right click, or start a drag without using the mouse. It should also have a free cursor mode from the menu, where I can move the pointer with H J K L or arrow keys, click with Space, right click, and scroll with a few simple keys.

Please make it feel polished and practical, with a preferences panel for changing the overlay shortcut and the key that closes the grid. It should save settings locally, work with macOS accessibility permissions, and show up cleanly in the menu bar. If anything needs checking against current macOS behavior, look up the latest docs online.
