/**
 * Unified wizard integration test — exercises the `skipGateway: false` code
 * path so that wiring between `runWizard` and the two gateway stages is
 * covered. The gateway stages themselves are mocked (they require a real
 * daemon + network) but the dynamic imports and option plumbing are real.
