- qaoa_adapter.py: fix finsler_metric_to_qubo to store Q_ij + Q_ji per
undirected pair; update is_anisotropic and _find_anisotropic_pair to
accept raw_matrix so asymmetry detection still works after summation;
add measure option to pauli_to_cirq.
- benchmark_finsler_qaoa.py: new benchmark harness for Finsler-Randers
routing via QAOA.
