        A node is considered healthy if its Stacks tip height matches the maximum Stacks tip height observed among its connected peers.

        This endpoint returns:

        - `difference_from_max_peer`: The difference in Stacks height between this node and its most advanced peer.

        - `max_stacks_height_of_neighbors`: The maximum Stacks height observed among the node"s connected peers.

        - `node_stacks_tip_height`: The current Stacks tip height of this node.

        - `max_stacks_neighbor_address`: The address of the most advanced peer. Null if no peer data is available.
