pnpm's default strict isolation hides @babel/runtime/helpers/* and other
transitive deps from Metro, which expects flat node_modules layout.
Each missing dep was a separate failed EAS build (metro-runtime,
@babel/runtime, ...) — added .npmrc with public-hoist-pattern entries
that catch the common RN/Expo families so we stop whack-a-moling them.
Also kept @babel/runtime as direct dep of @chat-app/mobile for safety.
expo-router@4 imports @expo/metro-runtime as the very first thing in its
entry-classic.js so Fast Refresh works; bundler errored without it.
Also dropped expo-router/babel from babel.config.js — its functionality
moved into babel-preset-expo in SDK 50.
Phase 0 installed expo-application/expo-image-picker/expo-dev-client at
^55.x assuming the major version matched the SDK number. It doesn't —
each expo-* package has its own major. Misaligned versions pulled in
expo-modules-core@2.2.3 which expects an API that SDK 52's gradle plugin
host doesn't provide, breaking the Gradle build with
'expo-module-gradle-plugin not found'.
`expo install --fix` aligned everything to SDK 52 baselines:
expo-application 55.0.15 -> ~6.0.2
expo-dev-client 55.0.33 -> ~5.0.20
expo-image-picker 55.0.20 -> ~16.0.6
expo-sqlite 15.0.6 -> ~15.1.4
react-native 0.76.0 -> 0.76.9
+ RN companion libs (gesture-handler, screens, async-storage)
