feat(aibox): 后台进程池 v3.8——智能体运行/管理长驻进程与交互式 I/O
新增 ProcessManager 子系统 + 5 个 worker 执行面工具 (bg_run/bg_write/bg_list/bg_output/bg_kill),弥补 run_command 同步阻塞、超时即杀的不足;run_command 原路径零改动。 - 生命周期三决策:用户中断不影响后台进程;aibox 退出经 atexit 收尾(非 detach 全杀,detach=true 豁免);注册表跨会话/跨子代理 全局共享 - 交互式 I/O:stdin 管道 + watermark 写读对齐(bg_output(since= watermark) 必然且仅为本条输入的响应);wait_lines expect 式同步 等待;写入 watchdog 线程兜底防管道写满阻塞 - 输出缓冲:每进程 256KB 环形缓冲(单行截断 16KB);log_file=true 同步 tee 无界全档,可被原生工具 tail/cat 读取 - 三级优雅终止:关 stdin → SIGTERM 宽限 → SIGKILL 兜底 - 安全边界:运行上限 16/条目上限 32/单次写入 64KB;background_ processes 配置节双闸;proc_name 规整规避 execute_tool 首参撞名 - 测试:test_process_manager.py 39 项(生命周期/游标续读/环形淘汰/ watermark 对齐/EOF 优雅终止/log tee/工具分发),全量 532 passed / 4 failed(平台环境项,与基线一致)零回归
