-Implement dual CJS/ESM build system following apollo-server's established pattern. This resolves type checking issues with different module formats by providing proper dual exports that allow the package to work seamlessly with both CommonJS and ES Module projects.
+The package is now built for both CJS and ESM, instead of only for CJS; this is the same build approach taken by `@apollo/server`. This provides better compatibility with ESM-based build systems.
