"""每席位「推理深度覆盖」（seat_modes）在进程内网关 run_seat 的解析测试。

语义（与前端 useStep2Orchestration「覆盖优先、否则跟随链条级 selectedMode」逐席位对齐）：
- 席位命中 seat_modes → 用该档（_SEAT_MODE_PARAMS）派生的 thinking/reasoning/subagent **覆盖**
  作业级 seat_*（不论作业级是什么）；
- 席位未命中 → 跟随作业级 seat_thinking_enabled / seat_reasoning_effort / seat_subagent_enabled；
- 作业级仍为 None → 落 policy("seat") 默认。

只验证传给 _run_agent_turn 的三个运行参数，故把 _run_agent_turn / policy / 文本解析全部打桩，
不触发真实 LLM / 沙箱。
