A Zod schema that validates array-like structures including mutable and readonly variants.
This schema validates values that behave like arrays, including standard arrays, tuples with rest elements, and their readonly counterparts. It accepts any array-like structure that can hold elements of any type, making it useful for validating collections where the specific array mutability or tuple structure is not critical.
