feat: xmpp bot最终修复版+skill文档同步

xmpp_agent_core.py 当前工作配置记录:
1. send_presence() — presence = available, 否则私聊进离线
2. 入站消息队列(_inbound_queue) — 崩了不丢, 重试3次
3. 出站队列(_outbound_queue) — 崩了自动重启
4. XMPP心跳检测(xep_0199 ping) — run_filters死后15s内重连
5. 私聊回复双通道: send_message(指定resource) + send_stanza(裸JID)
6. AGENT_MENTION动态解析(群聊@知微识别)
7. session_id保持xmpp-zhiwei-v2不变(不因重启换session)
8. 断线重连2秒延迟(防资源冲突)
