r"""问答管线（P12）：从详情层 `serve.py` 搬来的 `_ask_worker`/`_ask_step_text` 与相关常量。

★搬运改动（仅三处，其余逐字保留）：
  1. `_ask_worker` 加参数 `st`（详情层是"线程 + 全局 ASK"，这里改"同步 + 传入状态字典"）；
  2. 体内 `ASK['x']` → `st['x']`（`_on_step` 在 worker 内定义，闭包自然拿到同一个 st）；
  3. 对外只暴露 `ask_run(q, model, cat, xrev, lang)`：建 st、按 `ask_start` 的 hints 逻辑拼词、跑管线、收尾 state。
