Firstly thank you kindly for this project and consideration of this feature request!

What I would like to propose is printing all response codes and strings to stderr for skysh utility (and/or other utils)
That would in my opinion simplify parsing and working with CLI utility in scripts or in command line.

Rationale is this example:
This would parse also response (Okay) but if this fail I will never know until I see full stdout.
Example: skysh -e "lskeys" |grep Ok

If we want to handle more use cases, we talked about --output=stderr that could change behaviour of printing based on this option.
Also simple -q --quite flag could mitigate all reponses if we only want data output to stdout.
