feat(expo): support Expo SDK 57

[marc-wilson]

Current Behavior

@nx/expo only supports up to Expo SDK 56. Expo SDK 57 was released on June 30, 2026 (bringing React Native 0.86), and Nx workspaces have no supported path to it — generating or upgrading an Expo app in Nx is stuck on SDK 56 while create-expo-app and the rest of the Expo ecosystem are already on SDK 57.

This is out of date for roughly a month at this point, and given the cadence of Expo SDK releases, Nx is likely to keep falling further behind unless SDK support is picked up more proactively.

Expected Behavior

@nx/expo should support Expo SDK 57, in line with how #35714 tracked SDK 56 support previously.

GitHub Repo

No standalone repro repo — reproducible in any Nx workspace using @nx/expo.

Steps to Reproduce

1. In an Nx workspace, run npx nx g @nx/expo:application test-app.
2. Attempt to upgrade the generated app's Expo/React Native dependencies to SDK 57.
3. Note that @nx/expo (and its generators/executors) only support SDK 56 at this time.

Additional Information

• Expo SDK 57 changelog: https://expo.dev/changelog/sdk-57 (released June 30, 2026)
• Follows on from feat(expo): support Expo SDK 56 #35714 (SDK 56 support request) and bug(expo): generated Expo app uses legacy Metro/Babel setup instead of Expo Router structure #36442 (Expo generator output is stuck on the legacy Metro/Babel setup) — the version gap and the outdated generator scaffolding are separate but related symptoms of @nx/expo lagging behind current Expo tooling.
