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.

+# Download a pinned scrcpy-server.jar release, verify SHA-256 against an
+# in-script allow-list, and install it into app assets. Idempotent.
+#
+# Usage:
+#   scripts/update-server            # use DEFAULT_VERSION below
+#   scripts/update-server 4.0        # use explicit version
+#
+# Bumping to a new release:
+#   1. Run with the new version. The script will print the observed SHA-256
+#      and exit non-zero if it is not in the allow-list.
+#   2. Paste the printed line into the `case` below.
+#   3. Update DEFAULT_VERSION.
+#   4. Re-run. Commit the assets.
