GraphQL Codegen Compiler (legacy v0.x)

This package is the legacy compiler engine for GraphQL Code Generator v0.x, used to process GraphQL schemas and generate TypeScript types, React hooks, or other artifacts. The current stable version is 0.13.0, which is part of the now-deprecated v0.x line. It was replaced by `@graphql-codegen/cli` and `@graphql-codegen/plugin-helpers` in GraphQL Code Generator v1+, which introduced a new plugin-based architecture. This compiler is not compatible with v1+ plugins and should not be used in new projects. Key differentiator: it is a monolithic compiler that takes a schema and outputs code through a single pipeline, unlike the modular v1+ system that uses independent plugins.
