 * N4c V2: usePreviewHistory hook export-shape smoke test.
 *
 * Design note:
 * usePreviewHistory spins backend calls + debounced save timers via useEffect.
 * Under the worker-fork pool the ipcBridge / httpBridge chain never settles
 * (plan §2.4 WS reconnect hazard), and the hook hangs waitFor() indefinitely.
 * We therefore validate the module surface only; functional behavior is left
 * to e2e. This is recorded in N4c-final.md Deviations.
