Two runtime .unwrap() calls in the event loop are replaced with
explicit error logging and process::exit(1):
1. event::EventQueue::new() — fail to create event queue
2. event_queue.subscribe() — fail to subscribe to scheme events
Previously these panicked the daemon if the event subsystem
was unavailable. Now they log a clear error and exit gracefully.
Resolves IMPROVEMENT-PLAN §3.6: 'usbscsid: Fix .expect() in runtime'.
