Expo Go 54 (latest available on device) cannot run SDK 55 projects. Rewrite package.json with canonical SDK 54 versions from expo-template-tabs: expo ~54.0.33, expo-router ~6.0.23, react 19.1.0, react-native 0.81.5 expo-sqlite ~15.0.6, expo-document-picker ~13.1.6, expo-file-system ~18.0.12, expo-background-fetch/task-manager ~13.1.6, expo-notifications ~0.32.16, expo-constants ~18.0.13, expo-linking ~8.0.11, expo-splash-screen ~31.0.13, expo-status-bar ~3.0.9, react-native-screens ~4.16.0, react-native-safe-area-context ~5.6.0 TypeScript compiles cleanly; npm install completes without errors.
react-dom@19.2.5 (pulled by @expo/router-server) requires react@^19.2.5; @react-native/virtualized-lists@0.85.2 requires @types/react@^19.2.0. npm install now completes without errors or warnings.
react-native@0.85.2 requires react@^19.2.3; package.json had 19.0.0. Also update @types/react to ~19.1.0 to match.
