Description

One Line Summary

Add "WITH SOUND" push notification button to the demo app, document sound file setup, and harden the setup script.

Details

Motivation

The demo app was missing the "WITH SOUND" notification type specified in the shared demo build spec. This aligns the React Native demo with the Expo plugin demo (bff6ac79).

Scope

• Demo app: Adds WithSound notification type that sends a push with ios_sound: "vine_boom.wav" and android_channel_id for custom sound playback
• Sound file: Bundles vine_boom.wav in iOS app bundle (ios/demo/) and Android res/raw/, plus Xcode project configuration
• Build docs: Documents sound file placement paths for both platforms in examples/build.md
• Setup script: Adds set -euo pipefail for fail-fast behavior and fixes stale tgz cleanup glob
• No SDK changes

Testing

Manual testing

• Verified the "WITH SOUND" button sends a notification with custom sound on both iOS and Android
• iOS: sound plays correctly via ios_sound parameter
• Android: sound plays correctly after fresh install (channel created with vine_boom from res/raw/). Note: if the app was previously installed without the sound file, uninstall first so Android recreates the notification channel.
