Skip Play in-app update check for non-Play installs

AndroidAppUpdate now resolves the installer package and, when it is not com.android.vending (sideloaded, adb, other stores, debug builds), short-circuits updateAvailable to NoUpdateAvailable without building the Play requestUpdateFlow() pipeline. This avoids the Play update API call and its 'update available' notification on builds that can't be updated through Play.

Install source is read via getInstallSourceInfo() on API 30+ and the deprecated getInstallerPackageName() below it; any failure is treated as non-Play.
