hooks: trying to exit a client shell with the exporter offline is either freezes the client or prints unrelated error

[evakhoni]

if an exporter is momentary offline during an attempt exiting a jmp shell, the client will freeze. restarting an exporter in the background doesn't help.

[02/11/26 10:07:21] INFO     Running afterLease hook (Ctrl+C to skip)... [jumpstarter_cli.shell]                                                                                                                              

the behavior is intermediate, other times the client closes within a few seconds with Error: Ready for commands
