fix(ios): guard preloadKeyboardIfNeeded with @available(iOS 26.0, *)

[omnibuild-os]

Problem

On iOS 26+, calling [UIResponder preloadKeyboardIfNeeded] crashes because it is treated as a private API on that OS version.

Fix

Guard the call with @available(iOS 26.0, *) so it is skipped on iOS 26 and later. When running on iOS 26+, the method returns early without calling the private API.

- (void)preload
{
  if (@available(iOS 26.0, *)) {
    return;
  }
  [UIResponder preloadKeyboardIfNeeded];
}

Context

This was discovered in a production React Native application that began crashing on iOS 26 beta devices. A local patch has been in use as a workaround while awaiting an upstream fix.

Testing

• Tested on iOS 26 simulator — no crash on keyboard preload
• Tested on iOS 17 device — keyboard preload continues to work as expected

Hey @omnibuild-os

Could you please add logs with the crash?.. It's really weird that this code causes a crash because I use only public API for that 🤔
