experiments/test_tutte_bridge.py: bridge-derivability test for the dual of
the 46-vertex Tutte graph (a 25-vertex non-intertwining triangulation,
since the Tutte graph is non-Hamiltonian) -- the conjecture's first case
beyond the n=21 Holton-McKay duals. Reuses the fast integer-state bridge
engine: per source labelling with bipartite parity subgraphs, run a
backward bridge-orbit BFS for an Even Level Graph witness.
