The changes include refactoring the create-reader in cms keystatic and changing @keystatic/next version. Additionally, code generators for keystatic and package have been added, and corresponding templates have been organized into their respective directories.
Refactored the route handlers to use a new `enhanceRouteHandler` function for better control over request handlers and user authentication. CMS clients are now created using factory functions for better encapsulation and control over instance creation. Renamed `client.ts` in 'keystatic' to `keystatic-client.ts`.
