Marker for SDK-internal, transient activities (such as the notification-open trampolines) that must be excluded from app focus / foreground tracking.

These activities are launched by the SDK itself, often before the host app's real activity resumes, and they finish immediately after handling their intent. Counting them toward focus would prematurely toggle IApplicationService.isInForeground / entry state and corrupt the activity reference count once the SDK observes the full activity lifecycle from process start.
