OTPClient in Breadstick

Breadstick runs Debian's own otpclient package for ARM64, the build a Debian 13 computer with an ARM processor installs, so OTPClient should look and behave as it does on a Linux PC. On Samsung DeX, Floating mode opens it as its own window beside your Android apps, and Desktop mode runs it on a full Linux desktop.

There is no systemd, and the kernel, disks and network hardware belong to Android, so tools that work with files and processes behave as usual and tools that manage services or drivers have nothing to act on. More about system tools in Breadstick.
