Update React peer dependency to support 19.2

[Copilot]

Description

react-native@0.83.1 requires react ^19.2.0, but the package currently constrains to 18.2 - 19.1, causing ERESOLVE errors during installation.

Updated React peer dependency range from 18.2 - 19.1 to 18.2 - 19.2 in packages/app/package.json and regenerated yarn.lock.

Platforms affected

• Android
• iOS
• macOS
• visionOS
• Windows

Test plan

# Verify the peer dependency conflict is resolved
npx --package react-native-test-app@latest init --version 0.83

Should complete without ERESOLVE errors.

Original prompt

Problem

Issue #2637 reports that npx --package react-native-test-app@5.0.7 init fails with npm ERESOLVE error because:

• react-native@0.83.1 requires react ^19.2.0
• react-native-test-app@5.0.7 currently peers with react 18.2 - 19.1

This creates a peer dependency conflict that prevents installation.

Solution

Update the React peer dependency range in packages/app/package.json to support React 19.2:

Change the peerDependencies section:

"peerDependencies": {
  "@callstack/react-native-visionos": "0.76 - 0.79",
  "@expo/config-plugins": ">=5.0",
  "react": "18.2 - 19.2",
  "react-native": "0.76 - 0.83 || >=0.83.0-0 <0.84.0",
  "react-native-macos": "^0.0.0-0 || 0.76 - 0.79",
  "react-native-windows": "^0.0.0-0 || 0.76 - 0.80"
}

Specifically:

• Change "react": "18.2 - 19.1" to "react": "18.2 - 19.2"

Update yarn.lock:
After updating package.json, regenerate the yarn.lock file by running yarn install in the repository root to ensure all dependencies are properly resolved.

Expected Outcome

• ✅ Resolves npm ERESOLVE error when initializing with react-native@0.83.1
• ✅ Maintains backward compatibility with React 18.2 - 19.1
• ✅ Supports React 19.2.x which is required by react-native@0.83.1
• ✅ Aligns with current stable React version (19.2.3)

Fixes #2637
