fix(aibox): Batch N 波次1~2——第八轮审计 T 系列速赢与并发正确性修复

Browse Source 
波次1 速赢批（7 项）：
- T8 ProcessManager watermark 取号与回显记账原子化（entry.lock 改 RLock）
- T9 LLM 非 200 响应抛出前 close，流式路径清 _current_response
- T13 _sanitize_log_msg 增加裸 sk- key 脱敏，异常构造点统一过脱敏
- T12 流式判定改共享 saw_complete 标志（排空后 empty() 恒 False 死逻辑），
  超长截断前移堵住非流式直发绕过 N8 输出预算
- T16/T17 三处 Popen 显式 encoding=utf-8 + errors=replace
- T18 detach/log_file/force 统一过 _coerce_bool（字符串 "false" 误判）

波次2 并发正确性批（6 项）：
- T4 registry 输出队列入口快照，不再向共享工具实例传播（跨会话串扰）
- T5 executor 单槽 _current_process 改令牌多槽注册表，_terminate_tree
  显式传 (proc, pgid)，finally 只注销自己槽位（防并发误杀进程组）
- T6 FailoverClient 冷却键改 id(client)，与 P6 去重键语义一致
- T7 stream_chat 拆普通方法+内部生成器，消除生成器延迟副作用清除取消标志
- T15 工具结果统一 TOOL_MAX_RESULT_LENGTH 截断（两条分支同口径）
- T24 非流式 execute() timeout 下限夹取 1s（该路径无 3600s 兜底）

测试：532 passed / 4 failed（平台环境项）/ 1 skipped，零回归
审计报告补记 §23 第八轮审计 + §24 Batch N 波次1~2 修复记录
