Function emit_if_hidden

atomic-cli/src/output/progress.rs:232–236

Write a completion message directly to stderr when the progress bar is hidden. `indicatif` defaults to a stderr draw target that suppresses itself when stderr is not a terminal. That is the right call for the *animation* — a spinner in a log file is noise — but `finish_with_message` goes through the same draw target, so the final outcome line disappeared along with it. A piped `atomic view switch

(pb: &ProgressBar, prefix: &str, message: &str)

/// So when the bar is hidden, emit the message ourselves. Plain text, no ANSI:
/// the consumer is a pipe, a CI log, or an agent.
fn emit_if_hidden(pb: &ProgressBar, prefix: &str, message: &str) {
    if pb.is_hidden() {
        eprintln!("{} {}", prefix, message);
    }
}

/// Finish a progress bar with a success message.
