feat: Phase 4 — AI对话引擎 + 多轮上下文 + 协作数据采集 + 失败告警 + 幂等性

Phase 4A: backend/feishu-bot/ai-chat.js — DeepSeek/通义千问 AI 模型接入
Phase 4A: backend/feishu-bot/context-manager.js — 多轮对话上下文管理
Phase 4B: push-broadcast.yml — 飞书群新广播通知
Phase 4C: backend/feishu-bot/collaboration-logger.js — 协作数据采集
Phase 4C: scripts/save-collaboration-log.js — persona-brain-db 数据对齐导出
Phase 4D: 三条链路 workflow 失败告警 → 飞书通知
Phase 4D: receive-syslog.js — 幂等性保护（相同 SYSLOG 不重复创建工单）
