Two service-worker leaks. Running jobs were only bounded by their watchdog, so a command flood could hold many timers and results for up to JOB_TIMEOUT_MS; cap concurrent jobs at 32 and reject beyond that, since a clear error beats an unresponsive worker. Window aliases were never removed, so storage kept an entry for every window the user had ever renamed. Prune aliases against the live window set on list, rename, and close rather than only on close, because windows also disappear without going through windows.close. Also extract the repeated job summary in perf.status into a helper.
