Can we make this ExpoAppBeta?

I left a few comments on the approach so we reduce the committed code for maintainability & a cleaner way to do this. This is mostly cosmetic, other than that, it's great work & we're on the right track!

let's go with expobeta

+    applied = updateExpoVersion(packageJson, latestVersion);
+    if (applied) {
+      writeExpoApp56PackageJson(packageJson);
+    }
+  }


Can we not commit the expo beta app to the git repo, instead make this script generate it on-the-fly with create-expo-app with the right expo version flag; then let's inject brownfield plugin into it from this script. WDYT @hurali97 @valentin-callstack ?

let's do 2 things:

ExpoAppBeta

let's make this script actually re-generate that dir - please see more here: https://github.com/callstack/react-native-brownfield/pull/363/changes#r3388048979

same here - let's do ExpoAppBeta

+- `ExpoApp56` - a canary Expo application used to test incoming Expo beta releases before support lands in the stable CI matrix
 - `AndroidApp` - the native Android application that integrates the RNApp AAR package (a "consumer" of the RNApp library); it comes in two flavors:
  - `expo` - which uses the artifact produced from `ExpoApp`
  - `vanilla` - which uses the artifact produced from `RNApp`
 - `AppleApp` - the native iOS application that integrates packaged XCFrameworks (a "consumer" of the RN apps); the Xcode project defines one target per consumed RN app:
  - `Brownfield Apple App (RNApp)` — vanilla; uses the artifact from `RNApp` (scheme **Brownfield Apple App Vanilla**, configuration `Release Vanilla`)
  - `Brownfield Apple App (ExpoApp54)` — uses the artifact from `ExpoApp54` (scheme **Brownfield Apple App Expo 54**, configuration `Release`)
  - `Brownfield Apple App (ExpoApp55)` — uses the artifact from `ExpoApp55` (scheme **Brownfield Apple App Expo 55**, configuration `Release`)
+  - `Brownfield Apple App (ExpoApp56)` — uses the artifact from `ExpoApp56` (scheme **Brownfield Apple App Expo 56**, configuration `Release`)


Let's do ExpoAppBeta + note it'll be generated on-the-fly, not committed, as in https://github.com/callstack/react-native-brownfield/pull/363/changes#r3388048979

LGTM!

Waiting on your review @hurali97 . After that + CI green, let's ship it!

Pull request overview

This PR introduces an automated “Expo beta” road-test path intended to validate upcoming Expo SDK beta releases (e.g., SDK 56) against the repo’s existing AndroidApp/AppleApp consumer builds before stable support is added.

Changes:

Add a script to detect the latest Expo beta, generate apps/ExpoAppBeta from ExpoApp55, and (optionally) apply the detected Expo version.
Add a scheduled GitHub Actions workflow to run Android + iOS road tests for the detected Expo beta and record success via an artifact marker / create issues on failure.
Add new Android flavor and iOS scheme/target + build scripts for the “expobeta” consumer variants.
