The react-native/jest-preset.js redirect was removed in #57481, but private/helloworld still referenced 'preset: react-native' in its Jest config, breaking 'yarn test' in the test_ios_helloworld CI job with: Validation Error: Module react-native should have jest-preset.js ... Migrate HelloWorld to the standalone @react-native/jest-preset package, matching the documented migration path.
