* Internal `fetch` used by the Next.js client router.
*
* When the Instant Navigation Testing API is enabled, the navigation lock may
* install a blocking override on `window.fetch` for the duration of a lock
* scope. To let internal fetches bypass the lock, callers go through a wrapper
* that falls back to the pre-lock fetch captured at lock-acquire time.
*
* When the testing API is not enabled, this calls window.fetch directly.
