fix(ios): derive the pod deployment target from React Native (Xcode 27)

[sunnylqm]

Problem

Since 10.56.0 the privacy manifest ships as a resource bundle. CocoaPods gives the resource bundle target (react-native-update-react-native-update_privacy) the podspec's platform version, which is hard-coded to 11.0. React Native's post_install raises the deployment target of pod targets, but not of resource bundle targets.

Xcode 27 supports iOS 15.0 and later only, and treats the out-of-range target as an error. Every non-Expo iOS app on 10.56.0–10.57.0 fails to build:

error: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 11.0, but the range of supported deployment target versions is 15.0 to 27.0.x. (in target 'react-native-update-react-native-update_privacy' from project 'Pods')

CI did not catch it because it runs Xcode 26.4, where this is only a warning. Expo projects are not affected: their target is parsed from ExpoModulesCore.

Fix

Use React Native's min_ios_version_supported, as the library templates do. react_native_pods.rb defines it, and the Podfile loads that file before evaluating podspecs. The value never exceeds the app's own target, so pod install keeps working on older React Native versions. The spec falls back to 11.0 when the Podfile does not load react_native_pods.rb.

Verification

• Xcode 27.0, React Native 0.83: the react-native-update-react-native-update_privacy target failed to build before the change and built after it. The generated Pods project no longer contains DEPLOYMENT_TARGET = 11.0.
• The iOS E2E in CI (Xcode 26.4) covers regressions on the current toolchain.

Workaround for 10.56.0–10.57.0

Add this to the Podfile's post_install:

installer.pods_project.targets.each do |t|
  next unless t.name == 'react-native-update-react-native-update_privacy'
  t.build_configurations.each { |c| c.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '15.1' }
end
