TreeNode<T> class final

One node in the snapshot returned by Query.watchWithTree. Carries the parent CItem<T> and the per-sub-collection branches — each branch keyed by its SubSpec.subName and holding the current list of children at that level (which are themselves TreeNodes, recursing all the way down).

Children are TreeNode<dynamic> because Dart's type system can't thread the per-level generic parameter through a heterogeneous recursive structure without codegen. App code that knows the topology can branches['comments']!.cast<TreeNode<Comment>>().
