Section 26.6 - Max-flow min-cut theorem (legacy compatibility path)
Third-edition-numbered compatibility path for the max-flow min-cut theorem. The canonical
fourth-edition source is
CLRSLean.FourthEdition.Chapter_24.Section_24_6_MaxFlow_MinCut;
this module forwards to it so legacy imports keep working during the
compatibility period (see docs/migrations/clrs4.md).
