let formatter = JsonFormatter;
let mut output = UserOutput::with_formatter_override(
    VerbosityLevel::Normal,
    Box::new(formatter)
);

output.progress("Starting process");
// Output: {"type":"ProgressMessage","channel":"Stderr","content":"⏳ Starting process","timestamp":"2025-11-04T12:34:56Z"}
