Pull Request Overview

This PR adds support for Zod v4 to the GraphQL Code Generator validation schema plugin. The implementation introduces a new zodv4 schema type with updated type definitions and enum handling compatible with Zod v4, while providing backward compatibility through a new zodImportPath configuration option.

Key Changes

• Added zodv4 schema type with updated type system for Zod v4 compatibility
• Introduced zodImportPath configuration option for custom Zod import paths (e.g., zod/v3 compatibility layer)
• Fixed a type error in the YUP implementation for better enum handling
