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).
