fix: prevent duplicate RSC requests when navigation happens during inflight prefetch When a prefetch is already in progress (Pending status), navigation was immediately making a new RSC request instead of waiting for the prefetch to complete. This caused duplicate requests when users clicked links quickly after prefetch started. This fix adds: - Promise field to PendingRouteCacheEntry to track waiting navigation - waitForRouteCacheEntry function to wait for pending prefetch completion - Navigation logic to wait for inflight prefetch before making new request - Test to verify only one request is made when prefetch is inflight Fixes #86400
