Tiebreaker for equal-strength pairs: prefer the pair where more voters
expressed a preference (higher total participation). Meaningful only when the
matrix comes from matrixFromBallots (raw counts). With antisymmetric
matrices, total = value + (-value) = 0 for every edge — all pairs compare
equal, so the group falls back to simultaneous processing and ties are
preserved.
