Struct FocusTracker 

pub struct FocusTracker { /* private fields */ }

Focus tracker using xdg-desktop-portal

This tracker monitors window focus changes on Wayland compositors via the xdg-desktop-portal API. When the portal is unavailable, it gracefully degrades and provides a no-op implementation.
