feat(liblogc): 统一集中式日志客户端库 + 全量迁移
新增: - liblogc/: C++ 统一日志库 (libus_logc.so)，支持 set_endpoint/set_service_name/set_level - pymsg/pymsg/logc.py: Python 统一日志模块，基于 AsyncRpcQueue C++ 迁移 (删除 6 份本地 LogC.hpp 副本): - ca, gateway: <us/LogC.hpp> + set_service_name - captcha2, confs2, smtp3: using qing::LogC + set_service_name - core: ConfsLogC → qing::LogC (ConfsTask.cpp) - 所有 Makefile 添加 -lus_logc Python 迁移 (6 个 log_client.py → 4 行薄包装): - smtp, redirect80, confs, captcha, dnfs, static - 全部委托到 pymsg.logc.LogClient Go (waf): 保持现状，自成体系

/*
|

* LogC.hpp — smtp3 异步日志客户端（简化版）
|
||||
*
|
||||
* 基于 libmsg AsyncQueue，异步批量推送日志到 db:8005 的 Logs 表。
|
||||
* - 内存队列 + 后台线程攒批（满 50 条或 2 秒 flush）
|
||||
* - fail-safe：db 不可用时静默丢弃
|
||||
* - P3-5: 长连接复用（底层 openConnection + pmsg_send/recv），
|
||||
* 不再每批新建 TCP 连接；连接故障时关闭重建，本批丢弃
|
||||
* - API: info() / warning() / error()
