Pull request overview
This PR removes Expo SDK 54 support from the repo by deleting the ExpoApp54 example app and stripping all pre-55 Expo-specific code paths (templates, iOS Podfile/Xcode helpers, docs, and consumer build variants), leaving Expo SDK 55+ as the supported baseline.
Changes:
- Removed the
apps/ExpoApp54workspace and all related CI/local scripts, consumer app build flavors, and documentation. - Simplified the Expo config plugin implementation by dropping pre-55 handling (iOS patch script phase + Podfile hook logic; Android pre55 template path).
- Updated docs and changesets to reflect the new supported Expo SDK range.
