Section 17.1 - Amortized analysis methods (legacy compatibility path)

Third-edition-numbered compatibility path for the amortized-analysis methods. The canonical fourth-edition source is CLRSLean.FourthEdition.Chapter_16.Section_16_1_Amortized_Framework; this module forwards to it so legacy imports keep working during the compatibility period (see docs/migrations/clrs4.md).
