scrcpy-android: mirror an Android device over wireless ADB0.1

Native Java app for Android 12+ that mirrors another Android
device over wireless ADB, forwarding video, audio, touch input,
and clipboard. Bundles a pinned scrcpy-server.jar and the
vendored libadb-android stack. Supports h264/h265/av1 video and
raw/opus audio with in-app codec selection. No NDK, no Kotlin.
Includes JVM unit tests and a Docker-based emulator e2e rig.
