[Bug] Permission request UI flashes before hook auto-approval completes

Bug Description
When a PermissionRequest hook is configured to auto-approve certain commands, the permission request UI briefly flashes on screen before the hook completes and dismisses it. The hook does work correctly, but the visual flicker is distracting. Likely related to the hook and UI permission request running concurrently via Promise.race in createCanUseTool() (#44157) — the UI starts rendering immediately rather than waiting for the hook result first.
