_AVKit_GroupActivities cross-import overlay

This cross-import overlay bridges AVKit's video playback with the GroupActivities framework on visionOS, connecting media playback to SharePlay. It declares no types of its own; instead it supplies the integration that lets AVKit playback participate in a shared GroupActivities session. Import it alongside AVKit and GroupActivities to coordinate synchronized video experiences.

This module re-exports or extends other frameworks; it declares no public types of its own in the synthesized interface.
