+- Migrated action internals to ESM for compatibility with latest `@actions/*` packages. No changes to action inputs, outputs, or behavior.
+
+### Breaking change
+
+- The dummy `NODE_AUTH_TOKEN` fallback has been removed, as it could unintentionally affect the generated `.npmrc` with a non-functional token. With this change, if `registry-url` is set without `NODE_AUTH_TOKEN`, legacy Yarn Classic (1.x) and older Node/npm versions may fail, and pnpm may warn. npm Trusted Publishing (OIDC) is not affected, since it does not use `NODE_AUTH_TOKEN`.
