Expected sync behavior (mode: auto, from_node_root → debug_handle → id):
  Click linear in Graph 1 → Graph 2: add_tensor (last of {t,mm,add} with from_node_root=linear).
  Click t_default/mm_default/add_tensor in Graph 2 → Graph 1: linear (from_node_root match).
  Click relu in Graph 1 → Graph 2: relu_default (from_node_root=relu).
  Click relu in Graph 3 (union handle) → Graph 1: relu. Graph 2: relu_default.
