Add iOS App Clip support to Kid GO app

[Copilot]

This PR implements iOS App Clip functionality for the Kid GO app using the react-native-app-clip package, addressing issue #17.

What's Changed

iOS App Clip Configuration

• Added react-native-app-clip dependency (v0.6.1) compatible with Expo SDK 53
• Configured App Clip plugin in app.config.ts with optimized settings:
  • 16.0 deployment target for 15MB bundle size limit
  • Location confirmation and ephemeral notifications enabled
  • Proper bundle ID suffix configuration

Multi-Environment Support
The App Clip is automatically configured for all environments:

• Development: com.weshipit.kidgo.dev.Clip
• Preview: com.weshipit.kidgo.preview.Clip
• Production: com.weshipit.kidgo.Clip

Developer Experience

• Added utility functions in utils/app-clip.ts for:
  • Detecting if running as App Clip (checkIsAppClip())
  • Showing full app promotion overlay (showFullAppPrompt())
  • Conditional feature rendering (shouldShowAppClipFeatures())
• Updated README with App Clip documentation and testing instructions

Technical Details

The plugin automatically:

• Creates iOS App Extension targets with proper entitlements
• Configures parent-child app relationships
• Sets up bundle identifiers and signing capabilities
• Enables on-demand installation capability

Testing

To test the App Clip:

npx expo run:ios --scheme
# Select the App Clip scheme ending with "Clip"

The configuration has been validated across all environments and generates proper native iOS targets for App Clip functionality.

Closes #17

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• cdp.expo.dev
  • Triggering command: /usr/local/bin/node /home/REDACTED/work/kidgo/kidgo/node_modules/@expo/cli/build/src/utils/telemetry/clients/flushFetchDetached.js /tmp/aa25d80211397f1bee2d14198efb9568/expo-telemetry.json (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
