Function check_approval_with_tty 

pub async fn check_approval_with_tty(
    module_def: &Value,
    auto_approve: bool,
    is_tty: bool,
) -> Result<(), ApprovalError>

Internal implementation accepting is_tty for testability.

Delegates to check_approval_with_tty_timeout with DEFAULT_APPROVAL_TIMEOUT_SECS so existing callers keep the 60-second default.
