Claude (auto-RE) 22d2518847 re: don't let zombie emulators fool the liveness check
Container PID 1 is `sleep infinity` and never reaps, so every emulator this
script kills stays as a <defunct> entry that `pgrep -x` still matches -- after
a few captures the script always believed one was running. Same trap as the
Xvfb check. Ask ps for the process state and skip anything in Z.
