 **Cancellation is the manager's, not the signal's.** The dialog generates a request id for each run; the Host streams the run's output and phases under it, and `cancelInstall` answers only after pnpm exited and the files are back. The dialog waits for that answer before offering the spec again; an aborted RPC or a lost connection is not a confirmation. Only the check takes a trailing `AbortSignal`: going back or closing drops a registry lookup, whose settlement nothing waits for.
