v0.3.1 introduced TouchInterceptor (a FrameLayout wrapping the
ComposeView) so we could intercept touches before the inner MapView
saw ACTION_DOWN. That made the wrapper the window-root view (the
View actually attached to WindowManager) but I left the
ViewTreeLifecycleOwner / ViewTreeSavedStateRegistryOwner tags on
the inner ComposeView.
Compose's WindowRecomposer.create looks up findViewTreeLifecycleOwner
on the window-root, not on the inner ComposeView. With the tag
missing on the wrapper, Compose throws IllegalStateException at
composition startup — service crash on overlay enable.
Fix: move setViewTreeLifecycleOwner + setViewTreeSavedStateRegistryOwner
to the wrapper. v0.3.0 worked because the ComposeView itself was the
window-root then; the same pattern (owners on whatever's attached
directly to WindowManager) holds here.
