- direct_codex_error_code 原来对 ModelCallFailed 一律按宿主原文子串分类，ModelCallKind::TransportBroken 只有在原文恰好含 transport closed / 连接已关闭 时才会标成 transport-closed
- 改为先看 payload.kind：TransportBroken 直接给 transport-closed，其余 kind 仍按原文兜底（TODO 文本判据）
- 补用例 model_call_transport_broken_is_classified_from_the_typed_kind：原文不含任何分类标记，也只可能由 typed kind 得出该 code
