modes: [release, debug], release first as the default; build-apk.sh
already takes the mode as its last argument, which is how Dev Updater
passes it. enroll: goes through server/enroll-link.sh rather than the
binary directly, because the command is handed the app's mode too and
because the server may have been built in either profile -- the wrapper
ignores the word and takes whichever ai-server exists, release first.
