for that case.
I'll apply this one, but can you investigate a way to share this error
handling accross the tools?
A helper routine that doesn't call exit, but returns failure that will
then cause the tool to decide if it exits or what (TUI ones could
continue and the user could then select some other operation that would
work, etc).
It should standardize on ui__warning(), that already takes into account
if the UI is --stdio or --tui (in the future a GUI too), etc.
Thanks a lot!
