// Covers the "restart worker" footer feedback fix: RestartWorkerStatus used to be set but was
// never bound in any view, so a died-on-launch worker (e.g. a port conflict, see #292) restarted
// silently. RestartWorkerOperation is a test seam standing in for the real kill-and-relaunch +
// short-timeout survival check, so these tests only assert the success/failure routing to the
// shared footer strip (WorkerLogText/WorkerLogLevel), not real process spawning.
