// Inject an AVAudioSession "default to the loudspeaker" setup into the freshly-generated Capacitor iOS
// AppDelegate, so calls don't route to the quiet earpiece. Run on Codemagic (macOS) from ios-patch.sh:
//   node mobile/scripts/inject-audio.js mobile/ios/App/App/AppDelegate.swift
// TOLERANT by design: if the file is missing or the template doesn't match, it prints a note and exits 0
// so it can NEVER fail the build. First-pass fix — if iOS WebRTC re-grabs the session mid-call on device,
// we follow up with a plugin that re-asserts .overrideOutputAudioPort(.speaker).
