tests/attack_runaway.py — 越狱测试 d：失控长跑熔断 + 进程树回收（Agent-C）
========================================================================

  D1) 步数闸：mock runner 无限刷工具调用，max_steps=5 → 必须 breaker:max_steps，
      success=False，且 steps 精确停在 6（第 6 步触发）。
  D2) 超时闸（mock）：runner 死循环空转，timeout=5s → 必须 breaker:timeout，
      elapsed ≈ 5s（±3s 容差），success=False。
  D3) 超时闸（真实 pi 进程）：真实 pi headless 跑正常任务，timeout=15s
      （LLM 首响应通常 >15s）→ 必须 breaker:timeout 且 taskkill /T /F 后
      无 pi-coding-agent 相关 node 进程残留。

退出码 0 = 全部按预期；2 = 熔断失效或有进程残留。
