Could you build this?

Partial A tiling window manager's layout logic and config can be written with AI help in Zig, but macOS window control relies on Accessibility and sometimes private window-server APIs that are hard to get right without platform knowledge.

What it would actually take: The architecture is a background agent that observes and moves windows via macOS Accessibility APIs, plus hotkey handling via event taps and a layout engine. The hard parts are the undocumented or fragile window-server calls, handling SIP and permission prompts, and staying stable across macOS updates, which requires macOS internals expertise.
