`adb shell run-as` refuses on a release build — "package not debuggable" — and
the app's private storage is then unreachable from the host. That storage is
where the face shards, the thumbnail store and the catalog live, so when a
device disagrees with the desktop about what it has synced there is no way to
find out which of them is right. An evening was spent guessing at exactly that.
`DARKROOM_DEBUGGABLE=1 ./docker/android/package.sh --install` now sets
`android:debuggable` through aapt2's `--debug-mode`, and nothing else changes.
Set through aapt2 rather than written into `AndroidManifest.xml` on purpose: the
flag then exists only for the build that asked for it, and a release build
cannot inherit it because somebody forgot to take it out again. A debuggable APK
lets any process on the device read this app's files, so it belongs on a test
tablet and nowhere else.
