This branch is based on the changes from #43 and adds the missing Expo Android wiring for the actual generated MainApplication.kt shape.

What changed:

• handle Expo ReactNativeHostWrapper(...) templates by inserting a getJSBundleFile() override on the wrapped host
• keep the jsBundleFilePath path for templates that use getDefaultReactHost(...)
• add Expo Android regression coverage in test/test.ts so the generated MainApplication.kt is verified during test setup

Validation:

• npm run build:tests
• manually re-packed the plugin into a generated Expo app and ran expo prebuild --clean under Node 20
• verified the generated Android MainApplication.kt now contains CodePush.getJSBundleFile() wiring for the wrapper-based template

Notes:

• full Android emulator e2e could not run in this environment because the Android SDK tools (emulator, adb, sdkmanager) are not installed
• expo prebuild on the temporary app completed Android generation but later failed during iOS CocoaPods install due a minimum deployment target mismatch; Android output was generated before that failure
