Skill: Expo/React Native + Electric integration

[KyleAMathews]

Context

React Native with Expo is a supported platform for Electric + TanStack DB. AGENTS.md mentions react-native-random-uuid as a requirement, but the full setup story is more involved.

Scope

Create an electric-expo skill covering:

1. Prerequisites — react-native-random-uuid import in entry point, polyfills needed
2. Proxy setup — Mobile app → your API server → Electric (different from web proxy patterns)
3. Offline behavior — How Electric's HTTP-based sync behaves when mobile network drops
4. Background/foreground transitions — Visibility detection, reconnection on app resume
5. TanStack DB integration — Collections with React Native-specific considerations
6. Expo-specific setup — Metro bundler config, Expo Router API routes
7. Testing on device vs simulator — Network configuration, localhost vs LAN IP

Source

Identified during domain discovery skill test run. Maintainer confirmed React Native warrants standalone skill due to integration complexity.

Especially information on background/foreground transitions would be really appreciated - i think the Expo + TanStack DB example project also doesn't really handle those, right? Tried forceDisconnectAndRefresh(), but couldn't get the shape sync to resume after background->foreground.
