OneTap Install adds full XAPK and split APK handling

Modern Android games often ship as several APK files at once: a base package plus configuration splits for your device architecture, screen density and language. Install only one of them and the app either refuses to run or crashes on launch.

OneTap Install now reads the whole archive, works out which file is the base package, and commits every split in a single PackageInstaller session. That is the same mechanism Google Play uses, so the result is a clean, working install.

Why it matters

Users no longer need to know what a split APK is. They tap the file, confirm the system prompt, and the game works. Failed installs also stop deleting source files, so nothing is lost if something goes wrong.
