fix(examples): add sleep between AuditLogDemo emits to drain handlers

The async event handlers race with the main feature set. On macOS
CI the UserCreated handler didn't get CPU time before the process
moved on, causing a missing-line failure. Adding 100ms sleeps
between emits gives each handler time to execute and log.
