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 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
