主要更新内容
- 新增公开访客审计事件 RPC 端点（
public:recordVisitorEvent），需开启visitor_audit_enabled配置项，支持限流和字段规范化 - 移除 Nezha Agent gRPC 兼容层（配置项
nezha_compat_enabled/nezha_compat_listen及关联 proto 代码已删除） - 移除
metric_retention_days全局配置项，指标保留天数改为按定义单独设置（RetentionDays=0表示禁用持久化） - 默认关闭分层降采样（
metric_downsampling_enabled默认值改为false） - 内置指标默认保留期缩短为 1 天（仅影响新建实例的测试阶段）
- 增加 loong64 架构支持（Linux 二进制及安装脚本）
- 删除旧版监控数据缓存模块（
web/report/cache.go）和旧记录写入函数（WriteRecord/WriteGPURecord） - 指标报告改为批量写入（3 秒窗口、单事务提交），提高写入性能
- 删除客户端或 Ping 任务前自动清理关联的 metric store 数据
- 启动时增加 1.2.7 旧版监控数据迁移向导，支持进度显示和旧表清理
- 移除
Tag字段（JSON RPC 公共指标类型），改为 metadata - 添加迁移清理：移除数据库中旧的
metric_retention_days、nezha_compat_*配置项
Bug修复
- 加强访客审计日志的输入验证和限流，防止潜在滥用
- 修复零保留期指标定义在更新操作后数据未被清理的问题
- 修复 Ping 记录读取未使用 Series 接口导致无法处理降采样结果的问题
- 修复内建指标测试保留期过长的问题（改为 1 天）
其他
- 移除
util.SafeMap、secureconfig、ComputeTrafficDelta等废弃工具函数和文件 - 数据库日志表添加复合索引（
idx_logs_msg_type_time、idx_logs_time） - OAuth 初始化重构，启动阶段更清晰的依赖顺序
- 移除冗余的数据库函数（
EditClientName、GetAllTasksResultByUUID等）
