fix: 修复架构分析报告指出的P0问题
**AI 告警分析（P0）：** - 替换 setTimeout 伪AI为真实 LLM 调用 (aiApi.chat) - LLM 不可用时回退到规则模板（generateAIAnalysis） - 移除 Math.random() 随机置信度/相似案例 - 分析结果从 LLM JSON 响应解析 **SSH HostKey 验证（P0）：** - webshell.go: InsecureIgnoreHostKey → TOFU 模式 - agent_install.go: 同步修复 - 首次连接记录 SHA256 fingerprint 到日志 - 后续连接校验 HostKey 一致性 **Ansible 执行引擎（P0）：** - ExecutePlaybook 从模拟改为真实 ansible-playbook 调用 - 支持 extra-vars 参数传递 - 5分钟超时保护 - ansible-playbook 未安装时返回明确错误
