Struct CliError 

pub struct CliError(pub String);

A command that could not complete, carrying the message to print.

Every failing branch below returns one of these instead of calling std::process::exit where it stands: main.rs is the single place that prints and exits, so each command body stays a plain function a test can call and assert on.
