    Enable React Concurrent Rendering mode.

    When enabled:
    - Suspense boundaries work correctly with async data
    - `useTransition` and `useDeferredValue` are fully functional
    - Updates can be interrupted for higher priority work

    Note: Concurrent mode changes the timing of renders. Some tests may need to use `act()` to properly await updates. The `concurrent` option only takes effect on the first render for a given stdout. If you need to change the rendering mode, call `unmount()` first.
