Upgrade to React Native 0.83

Feature: Upgrade Expo TV app to SDK 55 and react-native-tvos 0.83

This PR upgrades the vega package to React Native 0.83 and @multitv/expotv package from Expo SDK 54 / react-native-tvos 0.81 to Expo SDK 55 / react-native-tvos 0.83.6-0.

Changes

Expo SDK upgrade (packages/expotv)

• expo ^54.0.20 → ^55.0.0
• react-native alias → npm:react-native-tvos@0.83.6-0
• react, react-dom 19.1.0 → 19.2.0
• All expo-* packages aligned to ~55.x via expo install --fix
• Native peer libs bumped: react-native-reanimated 4.2.1, react-native-gesture-handler ~2.30.0, react-native-screens ~4.23.0, react-native-worklets 0.7.4
• Added missing peer deps: expo-constants ~55.0.16, @expo/log-box 55.0.12, @babel/core ^7.25.0
• @types/react ~19.1.10 → ~19.2.10

Config cleanup (packages/expotv/app.json)

• Removed newArchEnabled: true (mandatory in SDK 55, no longer a valid field)
• Removed android.edgeToEdgeEnabled: true (now the default)

Testing

• yarn install resolves cleanly. The remaining peer warnings are pre-existing in the vega and shared packages and unrelated to this upgrade.
• yarn dlx expo-doctor reports 18/18 checks passing.

Notes for reviewers

• Node 20.19.4 or higher is required by SDK 55. Older Node will fail at expo CLI invocation.
• Native projects (android/, ios/) need to be regenerated via yarn expotv:prebuild after pulling this branch.
• The Vega package was deliberately not touched in this PR.
