## 变更内容
### CI/CD
- 添加 GitHub Actions 工作流（test + golangci-lint）
- 添加 golangci-lint 配置，启用 errcheck/govet/staticcheck/unused/depguard
- 通过 depguard 强制 service 层不能直接导入 repository
### 错误处理修复
- 修复 CSV 写入、SSE 流式输出、随机数生成等未处理的错误
- GenerateRedeemCode() 现在返回 error
### 资源泄露修复
- 统一使用 defer func() { _ = xxx.Close() }() 模式
### 代码清理
- 移除未使用的常量
- 简化 nil map 检查
- 统一代码格式
