Chapter 3 - Growth of Functions

This legacy guide forwards to the native fourth-edition Chapter 3 guide CLRSLean.FourthEdition.Chapter_03. The third-edition-numbered section imports CLRSLean.Chapter_03.Section_03_1_Asymptotic_Notation and CLRSLean.Chapter_03.Section_03_2_Standard_Functions also forward to the native fourth-edition sources during the compatibility period (see docs/migrations/clrs4.md).
