/**
 The `use_expo_modules_tests!` harness does not link companion pods, so the worklets adapter
 never registers `WorkletsProviderRegistry.shared`. That nil-provider state is exactly an app
 where `react-native-worklets` isn't installed — so this is the right place to assert that a
 worklet operation fails with the actionable `WorkletsNotInstalledException` rather than a
 misleading lower-level error (e.g. "not an instance of Worklet").
