Amplify GraphQL Auth Transformer

The `graphql-auth-transformer` is a core, internal component of the AWS Amplify CLI's API category, specifically designed to process the `@auth` directive within GraphQL schemas. It allows developers to declare comprehensive authorization rules directly in their GraphQL Schema Definition Language (SDL), which the Amplify CLI then translates into corresponding AWS AppSync resolvers, AWS Identity and Access Management (IAM) policies, and Amazon Cognito User Pool configurations. This package is part of the larger `@aws-amplify/amplify-category-api` umbrella, which receives frequent updates, with the current package version being 7.2.82. Its primary differentiator is simplifying the definition and deployment of granular access control for GraphQL APIs powered by AWS AppSync, abstracting away much of the underlying complex AWS security primitives into declarative schema directives. It significantly reduces the boilerplate traditionally associated with securing GraphQL endpoints on AWS, making robust authorization accessible to a wider range of developers.
