fix: correctly detect dumb terminal on Windows

Fix incorrect dumb-terminal detection on Windows

The current check for whether to hide the progress bar relies on reading the TERM environment variable directly:

let term_is_dumb_or_unset = match env::var("TERM") {
    Ok(term) => term == "dumb",
    Err(_) => true,
};

This treats an unset TERM as "dumb" and hides the progress bar.

On Windows, TERM is typically not set at all, even in perfectly capable terminals (Windows Terminal, PowerShell, cmd.exe, etc.), so this logic incorrectly hides progress bars on Windows in cases where they should be shown.

Behavior

Unset TERM environment variable is now treated as "not dumb" on Windows.

Note

This depends on is_dumb() being exposed from the console crate. See console-rs/console#290 for the corresponding change adding a public is_dumb() function.

• feat: add is_dumb public function console#290
• fix: respect NO_COLOR and TERM=dumb environment variable #808
