escolha pelo menos um formato de saída

Error message

escolha pelo menos um formato de saída

What it means

In run(), each enabled output format (json, txt/md, etc.) writes a file and pushes its path to `files`. If `files` is empty, no output format option was requested, so the tool aborts with this error rather than downloading the thread and producing nothing.

Solutions

1. Set at least one format flag to true, e.g. opts.json = true
2. Validate the options before invoking the download to fail fast
3. If multiple formats are desired, enable each one explicitly (files are written per enabled format)

Example fix

// before
let opts = ThreadOptions { dest: Some(dir), ..Default::default() }; // no format flag
// after
let opts = ThreadOptions { dest: Some(dir), json: true, ..Default::default() };

if !(opts.json || opts.txt || opts.md) {
    return Err(anyhow!("pick at least one output format before downloading"));
}

match run(&progress, opts).await {
    Err(e) if e.to_string().contains("formato de saida") => {
        eprintln!("no output format selected; enable json/txt/md in options");
    }
    Err(e) => return Err(e),
    Ok(_) => {}
}

When it happens

Trigger: Calling run() / baixa_uma_thread_publica_de_verdade with ThreadOptions where every format flag (opts.json, opts.txt, etc.) is false or omitted — validation happens after fetching but before the done report.

Common situations: Building options programmatically and forgetting to set any format flag; a config file defaulting all formats to false; UI passing only flags the user disabled.
