Revision counter for focus evaluation, e.g., skip Blueprint refresh when unchanged.
This numeric value (int32) belongs to FInteractionUIFocusProjection under InteractionUI.
Runtime and UI code should treat this as resolved state from the owning object. Read it to present, branch, or debug behavior without re-authoring the underlying interaction data.
