extends RefCounted

# Narrow construction boundary for Godot's MultiplayerPeer implementations.
# NetworkManager owns polling, RPC policy, and lifecycle; a transport only
# creates a peer.  Keeping that split means ENet remains a first-class path
# while Steam can use SDR without duplicating the rest of the networking code.
