29.2. Minimum-Cost Flow as an LP (legacy compatibility path)

Third-edition-numbered compatibility path for this module. The canonical fourth-edition source is CLRSLean.FourthEdition.Chapter_29.Section_29_2_Formulating_Problems_As_Linear_Programs.MinimumCostFlow; this module forwards to it so legacy imports keep working during the compatibility period (see docs/migrations/clrs4.md).
