Auto-Heal 通用守护

自动监测并修复HTTP、端口、进程等服务异常，支持回滚到稳定状态，防止级联故障并发送告警。

该技能的功能与描述一致：它从用户提供的 services.json 中读取检查和修复命令并执行。主要风险来自于它会执行配置内任意 shell 命令（eval），并把输出写入系统日志。 Before installing or running: - Treat services.json as highly privileged: only place commands you trust; never include plaintext passwords or credentials in commands. - Run the script under a least-privileged account (avoid root) or use sudo rules that limit what commands can be run. - Protect the config and log files with strict file permissions (chmod 600, owned by a dedicated user). - Prefer explicit, safe fix/rollback commands (avoid cmd type when possible) and avoid network calls to untrusted endpoints. - Consider code review or sandboxed testing on a non-production host first. - If you will add it to cron/autorun, ensure the cron entry runs as a controlled user and verify all configured commands. If you cannot guarantee trusted config and restricted runtime privileges, do not run this script in production.
