实现内容：
- 创建 trace/gin_logger.go，实现 GinLogger 和 GinRecovery 中间件
- GinLogger 自动记录所有 HTTP 请求的 method/path/status/latency/client_ip
- GinRecovery 使用 zap 记录 panic 恢复信息，替代 gin.Recovery()
- 修改 main.go 注册三层中间件：TraceMiddleware -> GinLogger -> GinRecovery
- 所有日志自动附加 trace_id 和 request_id 字段
日志示例：
{
"level": "info",
"ts": "2026-06-21T22:26:07.610+0800",
"msg": "request completed",
"trace_id": "01KVN964KSY6BFDKB9S932NXB8",
"request_id": "01KVN964KSY6BFDKB9S932NXB8",
"method": "GET",
"path": "/api/health",
"status": 200,
"latency_ms": 0,
"client_ip": "::1"
}
测试：已验证健康检查接口日志正常输出
