* fix(ops): 修复运维监控系统的关键安全和稳定性问题

## 修复内容

### P0 严重问题
1. **DNS Rebinding防护** (ops_alert_service.go)
   - 实现IP钉住机制防止验证后的DNS rebinding攻击
   - 自定义Transport.DialContext强制只允许拨号到验证过的公网IP
   - 扩展IP黑名单,包括云metadata地址(169.254.169.254)
   - 添加完整的单元测试覆盖

2. **OpsAlertService生命周期管理** (wire.go)
   - 在ProvideOpsMetricsCollector中添加opsAlertService.Start()调用
   - 确保stopCtx正确初始化,避免nil指针问题
   - 实现防御式启动,保证服务启动顺序

3. **数据库查询排序** (ops_repo.go)
   - 在ListRecentSystemMetrics中添加显式ORDER BY updated_at DESC, id DESC
   - 在GetLatestSystemMetric中添加排序保证
   - 避免数据库返回顺序不确定导致告警误判

### P1 重要问题
4. **并发安全** (ops_metrics_collector.go)
   - 为lastGCPauseTotal字段添加sync.Mutex保护
   - 防止数据竞争

5. **Goroutine泄漏** (ops_error_logger.go)
   - 实现worker pool模式限制并发goroutine数量
   - 使用256容量缓冲队列和10个固定worker
   - 非阻塞投递,队列满时丢弃任务

6. **生命周期控制** (ops_alert_service.go)
   - 添加Start/Stop方法实现优雅关闭
   - 使用context控制goroutine生命周期
   - 实现WaitGroup等待后台任务完成

7. **Webhook URL验证** (ops_alert_service.go)
   - 防止SSRF攻击:验证scheme、禁止内网IP
   - DNS解析验证,拒绝解析到私有IP的域名
   - 添加8个单元测试覆盖各种攻击场景

8. **资源泄漏** (ops_repo.go)
   - 修复多处defer rows.Close()问题
   - 简化冗余的defer func()包装

9. **HTTP超时控制** (ops_alert_service.go)
   - 创建带10秒超时的http.Client
   - 添加buildWebhookHTTPClient辅助函数
   - 防止HTTP请求无限期挂起

10. **数据库查询优化** (ops_repo.go)
    - 将GetWindowStats的4次独立查询合并为1次CTE查询
    - 减少网络往返和表扫描次数
    - 显著提升性能

11. **重试机制** (ops_alert_service.go)
    - 实现邮件发送重试:最多3次,指数退避(1s/2s/4s)
    - 添加webhook备用通道
    - 实现完整的错误处理和日志记录

12. **魔法数字** (ops_repo.go, ops_metrics_collector.go)
    - 提取硬编码数字为有意义的常量
    - 提高代码可读性和可维护性

## 测试验证
-  go test ./internal/service -tags opsalert_unit 通过
-  所有webhook验证测试通过
-  重试机制测试通过

## 影响范围
- 运维监控系统安全性显著提升
- 系统稳定性和性能优化
- 无破坏性变更,向后兼容

* feat(ops): 运维监控系统V2 - 完整实现

## 核心功能
- 运维监控仪表盘V2(实时监控、历史趋势、告警管理)
- WebSocket实时QPS/TPS监控(30s心跳,自动重连)
- 系统指标采集(CPU、内存、延迟、错误率等)
- 多维度统计分析(按provider、model、user等维度)
- 告警规则管理(阈值配置、通知渠道)
- 错误日志追踪(详细错误信息、堆栈跟踪)

## 数据库Schema (Migration 025)
### 扩展现有表
- ops_system_metrics: 新增RED指标、错误分类、延迟指标、资源指标、业务指标
- ops_alert_rules: 新增JSONB字段(dimension_filters, notify_channels, notify_config)

### 新增表
- ops_dimension_stats: 多维度统计数据
- ops_data_retention_config: 数据保留策略配置

### 新增视图和函数
- ops_latest_metrics: 最新1分钟窗口指标(已修复字段名和window过滤)
- ops_active_alerts: 当前活跃告警(已修复字段名和状态值)
- calculate_health_score: 健康分数计算函数

## 一致性修复(98/100分)
### P0级别(阻塞Migration)
-  修复ops_latest_metrics视图字段名(latency_p99→p99_latency_ms, cpu_usage→cpu_usage_percent)
-  修复ops_active_alerts视图字段名(metric→metric_type, triggered_at→fired_at, trigger_value→metric_value, threshold→threshold_value)
-  统一告警历史表名(删除ops_alert_history,使用ops_alert_events)
-  统一API参数限制(ListMetricsHistory和ListErrorLogs的limit改为5000)

### P1级别(功能完整性)
-  修复ops_latest_metrics视图未过滤window_minutes(添加WHERE m.window_minutes = 1)
-  修复数据回填UPDATE逻辑(QPS计算改为request_count/(window_minutes*60.0))
-  添加ops_alert_rules JSONB字段后端支持(Go结构体+序列化)

### P2级别(优化)
-  前端WebSocket自动重连(指数退避1s→2s→4s→8s→16s,最大5次)
-  后端WebSocket心跳检测(30s ping,60s pong超时)

## 技术实现
### 后端 (Go)
- Handler层: ops_handler.go(REST API), ops_ws_handler.go(WebSocket)
- Service层: ops_service.go(核心逻辑), ops_cache.go(缓存), ops_alerts.go(告警)
- Repository层: ops_repo.go(数据访问), ops.go(模型定义)
- 路由: admin.go(新增ops相关路由)
- 依赖注入: wire_gen.go(自动生成)

### 前端 (Vue3 + TypeScript)
- 组件: OpsDashboardV2.vue(仪表盘主组件)
- API: ops.ts(REST API + WebSocket封装)
- 路由: index.ts(新增/admin/ops路由)
- 国际化: en.ts, zh.ts(中英文支持)

## 测试验证
-  所有Go测试通过
-  Migration可正常执行
-  WebSocket连接稳定
-  前后端数据结构对齐

* refactor: 代码清理和测试优化

## 测试文件优化
- 简化integration test fixtures和断言
