feat: 🚀 增强会话管理与缓存机制 * 会话 ID 空值兜底,若 `conversation_id` 为空时自动生成 UUID * 在响应头写入 `X-Conversation-ID`,供前端使用,保持同一会话状态 perf: ⚡ 会话状态缓存优化 * 当缓存未命中但 DB 已确认/创建会话后,调用 `SetConversationStatus` 回写 Redis * 缓存写回失败时记录日志,不中断聊天主流程,确保业务流畅性 fix: 🐛 修复历史消息顺序问题与编译错误 * 修复历史消息顺序问题,保证返回的 N 条历史消息按时间正序喂给模型 * 通过反转 `created_at desc` 查询结果的切片,确保模型输入顺序正确 * 修复 `fmt.Errorf` 参数不匹配问题,修正编译错误 * 整理 `agent-cache.go` 为标准 UTF-8 编码,避免 Go 编译报错 `invalid UTF-8 encoding` feat: 🛠️ 独立构建 MCP 服务器 * 使用 `Codex` 构建独立于后端的 MCP 服务器,简化与 Codex 的协作 * 通过该服务器方便 Codex 直接测试和查看 Redis 与 MySQL 中的数据
