Android app launcher for iOS.

Drop in an APK, tap it, and the Android app opens full-screen.

GPL-2.0-or-later. Husk links QEMU, which is GPLv2, so the shipped binary is a combined GPLv2 work and the full source is public. It cannot go on the App Store — both because of that and because it needs get-task-allow plus a debugger attaching at runtime. See docs/01-licensing.md.
