Two final fixes from the live debugging session: (1) sdkmanager-latest
emulator 36.6.11 hangs before executing a single guest instruction in
this pod (KVM and TCG alike, every gpu mode, crash-reporting on or off)
while 36.1.9 boots Android in ~107s — the entrypoint now pins build
13823996 on the PVC; (2) the emulator already listens on 127.0.0.1:5555,
so socat's wildcard bind died with EADDRINUSE and its exit restarted the
pod right after a successful boot — socat now binds the pod IP only.
