+  * 全异步 asyncio 架构，单线程高并发 I/O；
+  * 彩色/文件双日志，结构化前缀、滚动保存；
+  * FFMPEG 自恢复与指数退避 + 抖动；
+  * HLS/HTTP 强化：-reconnect-* 自动断线重连，低延迟参数；
+  * 可选本地录制（独立进程，意外退出自动重启）；
+  * 优雅退出：SIGINT/SIGTERM，确保子进程回收；
+  * list.ini 热加载（mtime 变更即时生效）；
+  * 健康状态心跳（码率/时长/是否已推上帧）；
+  * 配置集中化：config.ini + 环境变量覆盖；
+
+依赖：仅标准库 + colorama + aiohttp
+保留你现有 spider/stream 模块调用约定。
