stop-server.sh read server.pid and SIGKILL'd that PID with no checks. After a
reboot or PID wraparound the pid file can point at an unrelated, live process —
which we would then kill.
Verify the PID is actually our server (a running 'node ... server.cjs') before
signalling it. If ownership can't be proven, fail closed: remove the stale pid
file and report {status: stale_pid} without killing anything. Real servers still
stop ({status: stopped}); a missing pid file still reports not_running.
Adds stop-server.test.sh covering: an unrelated reused PID is left alone, a real
server is stopped, and a missing pid file.
