T8b949e/**

* Renders node markers with clustering via the library's [Clustering] composable.

*

* Each unclustered node is composed as a [PulsingNodeChip] (`clusterItemContent`), with its z-index forwarded through

* [ClusteringMarkerProperties]; cluster bubbles keep the library's default rendering. Native info windows

* (title/snippet from [NodeClusterItem]) and click interactions are handled by the library renderer, and precision

* circles are drawn for the currently-unclustered items via `clusterItemDecoration`.

*

* Requires maps-compose >= 8.4.0: earlier versions composed cluster items into a detached `ComposeView` that carried no

* lifecycle/saved-state owners, crashing under the Navigation 3 hierarchy (fixed upstream in

* googlemaps/android-maps-compose#930, which this file previously worked around with a custom [DefaultClusterRenderer]

* assigning pre-baked bitmaps).
