When the /restart command runs inside an embedded agent process (no
SIGUSR1 listener), it falls through to triggerOpenClawRestart() which
calls launchctl kickstart -k directly — bypassing the pre-restart port
cleanup added in #27013. If the gateway was started via TUI/CLI, the
orphaned process still holds the port and the new launchd instance
crash-loops.
Add synchronous stale-PID detection (lsof) and termination
(SIGTERM→SIGKILL) inside triggerOpenClawRestart() itself, so every
caller — including the embedded agent /restart path — gets port cleanup
before the service manager restart command fires.
Closes#26736
