// Abstract-namespace UNIX socket transport (the '@'-prefixed path). Exercises
// the full UdsServer + Client RPC round-trip over an abstract socket, which is
// how the daemon runs where SELinux denies pathname sockets (unrooted Android /
// celltron). Stream I/O is done by stock bare-pipe; bare-abstract-socket only
// creates the socket. Linux-only (abstract sockets are a Linux extension).
