bitloi c832fad7b5 [2.x] feat: Notify sbtn client when command is queued (#8568) ... Fixes #8356 **Problem** When `sbtn` sends a command while another long-running task (like `console`) is already executing, the client silently blocks with no indication that the command is waiting in a queue. **Solution** When a new command arrives via the network channel and another command is currently running, the server now sends an `ExecStatusEvent` notification with status `"Queued"` to the client. The client displays a message like: ``` [info] waiting for: console ```		2026-01-16 16:17:00 -05:00
