/**
 * Fix für SDK-54 + prebuilt React Native + react-native-webrtc:
 *   "include of non-modular header inside framework module"
 *   (als Fehler, weil Xcode `-Werror=non-modular-include-in-framework-module`
 *    auf Framework-Module setzt).
 *
 * Ab RN 0.81 / Expo SDK 54 wird React Native als prebuilt XCFramework
 * (React.framework, modular) ausgeliefert. Native Module wie react-native-webrtc
 * importieren React-Core-Header non-modular (`#import "React/..."`) → das ist bei
 * modularen Frameworks ein -Werror → Build bricht ab.
 *
 * Lösung (dokumentiert): auf den Pod-Targets non-modular Includes erlauben
 * (CLANG_ALLOW_NON_MODULAR_INCLUDES_IN_FRAMEWORK_MODULES=YES) + das -Werror
 * neutralisieren (-Wno-error=non-modular-include-in-framework-module).
 *
 * Injiziert in den bestehenden `post_install do |installer|`-Block (ein zweiter
 * würde den ersten ersetzen). Idempotent via Marker. Läuft als
 * withDangerousMod('ios') während `expo prebuild`, vor `pod install`.
