virtual QString	neighborOutputInDirection (const QString &screenId, const QString &direction) const =0
	The connected output geometrically adjacent to `screenId` in `direction`, or an empty string when there is none.

virtual int	neighborDesktopInDirection (int currentDesktop, const QString &direction) const =0
	The 1-based virtual desktop reached by stepping `direction` from `currentDesktop` on the desktop grid, or 0 when there is none.

Detailed Description

Resolves the neighbouring surface — output or virtual desktop — in a direction, for cross-surface window navigation.

Implemented daemon-side over the screen-topology and virtual-desktop services and injected into the placement engines, so the geometry/desktop knowledge lives in exactly one place and the autotile and snap engines resolve crossings identically (the engines just ask). Both methods take the lower-case direction tokens "left" / "right" / "up" / "down".
