CNSheetGeometryProbe class

Invisible probe that lives at the root of a CNBottomSheet builder and publishes the sheet body's live global rect every frame.

Implementation: findRenderObject -> RenderBox.localToGlobal each frame via a self-rescheduling post-frame callback. Drag-to-dismiss updates the rect within one frame (post-frame schedules at end of layout, fires after paint — the rect published reflects the just- rendered frame; consumers via ValueNotifier see it on the next frame). On dispose, clears the published rect to null. Invisible widget that publishes its own global rect to CNTabBarRouteObserver.topModalRect each frame, then clears it on dispose. Use this manually inside any sheet/popup builder that CNBottomSheet doesn't wrap (e.g. Scaffold.showBottomSheet for persistent sheets) to opt that sheet into position-aware host-page CN-widget hiding.
