The LAN and dedicated servers built the tree from the data generator's
commands report, which sorts each node's children. lan/command_order.rs,
generated from vanilla's Commands(CommandSelection.ALL) by
tools/generate_lan_command_order.py, gives the registration order, and the
dedicated-server harness now compares the tree in order (the game rules,
registered in an identity-hashed order, aside).
