fix(lint): 修复 golangci-lint 错误 (119 -> 0 issues)

Browse Source 
主要修复：
- errcheck: defer Close 使用 //nolint:errcheck，类型断言改为 ok 检查
- govet fieldalignment: 调整结构体字段顺序优化内存布局
- revive unused-parameter: 将未使用参数改为 _
- exhaustive: 添加缺失的 switch case 或 default
- goconst: 提取重复字符串为常量 (accessAllow, accessDeny 等)
- staticcheck SA9003: 修复空分支逻辑
- gofmt: 运行 gofmt -w 格式化
- nolintlint: 修复 nolint 注释格式

其他改进：
- 更新 .golangci.yml 配置，启用更严格的检查
- 移除未使用的代码和导入
- 简化测试辅助函数调用
