Section 10.1 - Stacks and queues (legacy compatibility path)

Third-edition-numbered compatibility path for stacks and queues. The canonical fourth-edition source is CLRSLean.FourthEdition.Chapter_10.Section_10_1_Simple_Array_Based_Data_Structures; this module forwards to it so legacy imports keep working during the compatibility period (see docs/migrations/clrs4.md).
