Bug Fixes

• Fix non-deterministic SPQR decomposition caused by Python hash seed
  randomization. PathSearcher picked the DFS start vertex via
  next(iter(set)), whose iteration order varies with
  PYTHONHASHSEED. This produced different triconnected components
  (~50% of runs) for the same input graph. Now uses a deterministic
  start vertex derived from edge insertion order.
