Alternation of windows in the same zone

### Describe the feature you'd like
It would be great to have a way to switch between windows within the same zone or region — for example, using `Win + \`` to cycle only through windows occupying that same tiled area.
If possible, a visual GUI (preview or icon list) for those windows would be even more powerful, allowing fast contextual switching within a specific layout.

### Is your feature request related to a problem?
Right now, cycling through windows affects all open ones, which can break focus during tasks that rely heavily on working within one layout zone. Isolating the switch to a specific region would improve productivity and reduce noise.

### Additional context
Just yesterday I was tweaking my setup with AutoHotkey on Windows to improve my workflow using FancyZones — then I discovered this extension for Linux, and it's been incredible. It really brings me close to the same experience!
On Windows, I created a basic version of this idea using AHK: [toggleWindowSameZone.ahk](https://github.com/jjdevzinho/fancyWindows/blob/main/toggleWindowSameZone.ahk).
It’s functional, though pretty minimal, since building a GUI preview wasn't really my thing — but the concept works well by allowing zone-local switching.

Thanks again for this amazing project!
