feat(logging-p0): add structured logging to database driver services

Add createLogger/trackDuration logging to mysql.ts, sql-server.ts, and
data-source.ts — the only database layer files without observability.
Connect/disconnect, query execution (with duration tracking), and
transaction lifecycle events are now logged. Passwords and parameter
values are excluded; SQL statements are capped at 100 chars.

+
+## 日志最佳实践
+
+### 1. 开发环境 vs 生产环境
+
+```mermaid
+flowchart LR
+    A[日志级别配置] --> B{环境？}
+    B -->|开发 | C[DEBUG 级别<br/>详细信息]
+    B -->|生产 | D[INFO 级别<br/>业务操作]
+    C --> E[调试问题]
+    D --> F[监控运行]
+```
+
+**配置示例**：
+
+```yaml
+# config.yaml
+logging:
+  level: debug # 开发环境
+  # level: info  # 生产环境
+```
+
+---
+
+### 2. 敏感信息保护
+
+**永远不要记录**：
+
+- ❌ 密码
+- ❌ Token/密钥
+- ❌ 数据库连接字符串
+- ❌ 用户个人信息
+
+**正确做法**：
+
+```typescript
+// ❌ 错误：记录敏感信息
+log.error('Login failed', { password: userPassword })
+
+// ✅ 正确：使用脱敏信息
+log.error('Login failed', {
+  userId: 'admin',
+  reason: 'invalid_credentials' // 仅记录原因
+})
+```
+
+---
+
+### 3. 错误日志应该包含
+
+**完整上下文**：
+
+```typescript
+log.error('Database insert failed', {
+  requestId: getRequestId(), // 自动注入
+  operation: 'insert-materials',
+  userId: 'admin',
+  tableName: 'DiscreteMaterialPlan',
+  recordCount: 150,
+  error: error.message,
+  orderNumbers: ['SO001', 'SO002']
+})
+```
+
+---
+
+### 4. 性能监控
+
+**关键指标**：
+
+- `duration > 1000ms`：一般警告
+- `duration > 5000ms`：严重警告
+- `duration > 10000ms`：需要立即调查
+
+**监控脚本**：
+
+```powershell
+# 每小时生成性能报告
+Get-Content "C:\Users\pengq\AppData\Roaming\erpauto\logs\app-*.log" |
+  ConvertFrom-Json |
+  Where-Object { $_.duration -gt 1000 } |
+  Group-Object operation |
+  ForEach-Object {
+    [PSCustomObject]@{
+      Operation = $_.Name
+      SlowOperations = $_.Count
+      AvgDuration = [math]::Round(($_.Group | Measure-Object duration -Average).Average, 2)
+      MaxDuration = [math]::Round(($_.Group | Measure-Object duration -Maximum).Maximum, 2)
+    }
+  } | Format-Table -AutoSize
+```
+
+---
+
+## 日志文件管理
+
+### 文件位置
+
+| 环境     | 路径                                              |

+| **开发** | `D:\FileLib\Projects\CodeMigration\ERPAuto\logs\` |
+| **生产** | `C:\Users\<user>\AppData\Roaming\erpauto\logs\`   |
+
+### 文件命名
+
+| 类型     | 命名格式                 | 说明               |
+| -------- | ------------------------ | ------------------ |
+| 应用日志 | `app-YYYY-MM-DD.log`     | 所有业务日志       |
+| 错误日志 | `error-YYYY-MM-DD.log`   | 仅错误级别日志     |
+| 审计日志 | `audit-YYYY-MM-DD.jsonl` | 用户操作审计       |
+| 压缩归档 | `*.log.gz`               | 超过保留期限的日志 |
+
+### 保留策略
+
+```yaml
+# config.yaml
+logging:
+  appRetention: 14 # 应用日志保留 14 天
+  auditRetention: 30 # 审计日志保留 30 天
+```
+
+---
+
+## 故障排查流程图
+
+### 通用排查流程

+
+## 核心组件
+
+### 1. 主进程日志服务 (`src/main/services/logger/`)
+
+#### 1.1 核心日志器 (`index.ts`)
+
+```typescript
+// 日志器创建与配置
+import winston from 'winston'
+import DailyRotateFile from 'winston-daily-rotate-file'
+
+const logger = winston.createLogger({
+  level: 'info',
+  defaultMeta: { service: 'erpauto' },
+  transports: [new winston.transports.Console({ format: consoleFormat })]
+})
+```
+
+**关键特性：**
+
+- **双格式输出**：控制台（彩色文本）+ 文件（JSON）
+- **每日轮转**：日志文件按日期拆分，自动压缩归档
+- **错误序列化**：完整捕获 stack trace 和自定义属性
+- **环境感知**：生产环境自动脱敏敏感信息
+
+#### 1.2 日志级别与优先级
+
+```typescript
+export type LogLevel = 'error' | 'warn' | 'info' | 'debug' | 'verbose'
+
+export const LOG_LEVEL_PRIORITY: Record<string, number> = {
+  verbose: 0,
+  debug: 1,
+  info: 2,
+  warn: 3,
+  error: 4
+}
+```
+
+#### 1.3 错误工具类 (`error-utils.ts`)
+
+```mermaid
+flowchart LR
+    A[Error Occurs] --> B{Error Type?}
+    B -->|Error Instance| C[serializeError]
+    B -->|Error-like| C
+    B -->|Other| D[Wrap as UnknownError]
+    C --> E{Production?}
+    D --> E
+    E -->|Yes| F[sanitizeError]
+    E -->|No| G[Keep Full Details]
+    F --> H[Redact Sensitive Keys]
+    G --> I[Preserve Stack Trace]
+    H --> J[Log Output]
+    I --> J
+```
+
+**序列化流程：**
+
+1. 捕获所有 enumerable 和 non-enumerable 属性
+2. 递归处理 error cause 链
+3. 生产环境脱敏 password/token/secret 等敏感字段
+4. 提取堆栈中的文件/行号/列号信息
+
+---
+
+### 2. 审计日志服务 (`audit-logger.ts`)
+
+**用途**：记录用户操作审计日志，满足合规要求
+
+```typescript
+interface AuditEntry {
+  timestamp: string // ISO 8601 时间戳
+  action: string // 操作类型：LOGIN, EXTRACT, DELETE
+  userId: string // 用户 ID
+  username: string // 用户名
+  computerName: string // 计算机名
+  resource: string // 受影响的资源
+  status: 'success' | 'failure' | 'partial'
+  metadata: Record<string, unknown>
+}
+```
+
+**格式特点：**
+
+- **JSONL 格式**：每行一个 JSON 对象，便于流式解析
+- **30 天轮转**：默认保留 30 天审计日志
+- **独立文件**：`audit-YYYY-MM-DD.jsonl`
+
+---
+
+### 3. IPC 日志处理器 (`src/main/ipc/logger-handler.ts`)
+
+```mermaid
+sequenceDiagram
+    participant R as Renderer
+    participant B as Buffer State
+    participant W as Winston
+    participant F as File
+
+    R->>B: Send Log Entry
+    Note over B: Circuit Breaker Check
+    alt Error Level
+        B->>B: Always Buffer
+    else Non-Error & Buffer < 500
+        B->>B: Buffer Entry
+    else Buffer >= 500
+        B->>B: Discard + Count
+    end
+
+    Note over B: Batch Processing
+    B->>B: 100ms Debounce OR 50 entries
+    B->>W: Flush Batch
+    W->>F: Write to File
+```
+
+**批处理策略：**
+| 参数 | 值 | 说明 |
+|------|-----|------|
+| `DEBOUNCE_MS` | 100ms | 防抖等待时间 |
+| `MAX_BATCH_SIZE` | 50 | 最大批次大小 |
+| `CIRCUIT_BREAKER_THRESHOLD` | 500 | 熔断阈值 |
+
+**熔断机制：**
+
+- 当缓冲区 > 500 条时，丢弃非错误日志
+- 错误日志始终绕过熔断器
+- 每丢弃 100 条记录一次警告
+
+---
+
+### 4. 渲染进程日志 Hook (`src/renderer/src/hooks/useLogger.ts`)
+
+```typescript
+// 使用示例
+function MyComponent() {
+  const logger = useLogger('MyComponent')
+
+  const handleClick = () => {
+    logger.info('User clicked button', { buttonId: 'submit' })
+  }
+
+  const handleError = (err: Error) => {
+    logger.error('Operation failed', { error: err.message })
+  }
+}
+```
+
+**客户端级别过滤：**
+
+```typescript
+// 在发送 IPC 前检查日志级别，避免无效 IPC 调用
+if (!shouldLog(level)) return
+ipcRenderer.send(IPC_CHANNELS.LOGGER_FORWARD, { ... })
+```
+
+**FPS 监控：**
+
+- 检测因过度日志导致的 UI 卡顿
+- 当 FPS < 30 时发出警告
+- 5 秒冷却期避免重复警告
+
+---
+
+### 5. 预加载层 API (`src/preload/api/logger.ts`)
+
+```typescript
+// 级别缓存机制
+let cachedLevel: LogLevel = 'info'
+
+// 监听主进程级别变更广播
+ipcRenderer.on(IPC_CHANNELS.LOGGER_LEVEL_CHANGED, (level) => {
+  cachedLevel = level
+})
+
+// 客户端过滤
+function shouldLog(level: LogLevel): boolean {
+  return priorities[level] >= priorities[cachedLevel]
+}
+```
+
+---
+
+### 6. 配置管理 (`src/main/services/config/config-manager.ts`)
+
+```yaml
+# config.yaml 配置示例
+logging:
+  level: info # 日志级别
+  auditRetention: 30 # 审计日志保留天数
+  appRetention: 14 # 应用日志保留天数
+```
+
+**配置加载时机：**
+
+1. 应用启动时加载 `config.yaml`
+2. 调用 `applyLoggingConfig()` 配置 Winston
+3. 调用 `applyAuditConfig()` 配置审计日志
+

+## IPC 通道定义
+
+```typescript
+// src/shared/ipc-channels.ts
+export const IPC_CHANNELS = {
+  // 日志转发（renderer → main）
+  LOGGER_FORWARD: 'logger:forward',
+
+  // 获取当前日志级别
+  LOGGER_GET_LEVEL: 'logger:getLevel',
+
+  // 级别变更广播（main → renderer）
+  LOGGER_LEVEL_CHANGED: 'logger:levelChanged'
+}
+```
+
+---
+
+## 使用指南
+
+### 在主进程中记录日志
+
+```typescript
+import { createLogger } from '@/main/services/logger'
+
+const log = createLogger('MyService')
+
+// 基础用法
+log.info('Operation started')
+log.warn('Disk space low')
+log.error('Failed to connect', { error: err })
+
+// 带上下文的日志
+log.info('Processing batch', {
+  batchId: 'B001',
+  itemCount: 100,
+  estimatedTime: '5min'
+})
+
+// 错误日志（自动序列化堆栈）
+try {
+  await riskyOperation()
+} catch (error) {
+  log.error('Operation failed', { error })
+}
+```
+
+### 在渲染进程中记录日志
+
+```typescript
+import { useLogger } from '@/renderer/src/hooks/useLogger'
+
+function MyComponent() {
+  const logger = useLogger('MyComponent')
+
+  useEffect(() => {
+    logger.info('Component mounted')
+    return () => logger.debug('Component unmounted')
+  }, [])
+
+  const handleAction = async () => {
+    try {
+      await api.doSomething()
+      logger.info('Action succeeded')
+    } catch (err) {
+      logger.error('Action failed', { error: err.message })
+    }
+  }
+}
+```
+
+### 记录审计日志
+
+```typescript
+import { logAudit } from '@/main/services/logger/audit-logger'
+
+// 用户登录审计
+logAudit('LOGIN', userId, {
+  username: 'admin',
+  computerName: 'DESKTOP-001',
+  resource: '/auth',
+  status: 'success',
+  metadata: { loginMethod: 'password' }
+})
+
+// 数据提取审计
+logAudit('EXTRACT', userId, {
+  username: 'user1',
+  computerName: 'DESKTOP-002',
+  resource: 'materials',
+  status: 'success',
+  metadata: { orderCount: 50, materialCount: 1200 }
+})
+```
+
+---
+
+## 高级功能
+
+### 1. 日志级别动态切换
+
+```mermaid
+sequenceDiagram
+    participant U as User (UI)
+    participant C as ConfigManager
+    participant M as Main Logger
+    participant R as Renderer
+    participant L as Level Cache
+
+    U->>C: Update logging.level
+    C->>M: applyLoggingConfig(newLevel)
+    M->>M: logger.level = newLevel
+    M->>R: Broadcast levelChanged
+    R->>L: cachedLevel = newLevel
+    Note over L: Future logs filtered at client
+```
+
+**代码示例：**
+
+```typescript
+// 主进程设置级别
+import { setLogLevel } from '@/main/services/logger'
+setLogLevel('debug')
+
+// 渲染进程自动同步
+// useLogger Hook 会自动接收级别变更广播
+// 客户端过滤自动生效
+```
+
+### 2. 生产环境错误脱敏
+
+```typescript
+// 自动脱敏以下关键字段
+const sensitiveKeys = [
+  'password', 'secret', 'token', 'apiKey',
+  'credentials', 'authorization', 'privateKey'
+]
+
+// 生产环境错误消息
+{
+  "name": "AuthError",
+  "message": "An error occurred due to invalid credentials or configuration"
+  // 原始错误消息被脱敏
+}
+```
+
+### 3. 错误上下文提取
+
+```typescript
+// 从堆栈跟踪提取位置信息
+const errorContext = extractErrorContext(serializedError)
+// 输出:
+{
+  fileName: 'extractor.ts',
+  lineNumber: 142,
+  columnName: 15,
+  functionName: 'runExtraction'
+}
+```
+
+---
+
+## 最佳实践
+
+### ✅ 推荐做法
+
+```typescript
+// 1. 使用 createLogger 创建带上下文的子日志器
+const log = createLogger('DatabaseService')
+
+// 2. 记录错误时传递完整 Error 对象
+log.error('Query failed', { error })
+
+// 3. 使用结构化元数据
+log.info('Batch processed', {
+  batchId: 'B001',
+  duration: 1250,
+  itemCount: 100
+})
+
+// 4. 渲染进程使用 useLogger Hook
+const logger = useLogger('LoginForm')
+
+// 5. 敏感信息使用审计日志
+logAudit('DELETE', userId, { ... })
+```
+
+### ❌ 避免的做法
+
+```typescript
+// 1. 避免直接 console.log
+console.log('debug') // ❌ 不会被 Winston 捕获
+
+// 2. 避免只记录错误消息
+log.error(err.message) // ❌ 丢失堆栈和类型
+
+// 3. 避免循环引用元数据
+const obj: any = {}
+obj.self = obj
+log.info('test', { obj }) // ❌ 序列化失败
+
+// 4. 避免过度日志
+for (let i = 0; i < 1000; i++) {
+  logger.info(`Item ${i}`) // ❌ 触发熔断
+}
+```
+
+---
+
+## 故障排查
+
+### 问题：日志文件不生成
+
+**检查清单：**
+
+1. 确认 `config.yaml` 中 logging 配置正确
+2. 检查日志目录权限
+3. 查看控制台输出是否有 Winston 错误
+4. 验证 `applyLoggingConfig()` 是否被调用
+
+### 问题：渲染进程日志未到达主进程
+
+**调试步骤：**
+
+```typescript
+// 1. 检查 IPC 通道是否注册
+// src/main/ipc/index.ts 应包含：
+registerLoggerHandlers()
+
+// 2. 检查 preload 暴露
+// src/preload/index.ts 应暴露：
+contextBridge.exposeInMainWorld('electron', api)
+
+// 3. 检查级别过滤
+console.log(window.electron.logger) // 应存在
+```
+
+### 问题：生产环境错误信息不完整
+
+**原因**：生产环境自动脱敏
+**解决方案**：
+
+- 查看 `error-DATE.log` 获取完整错误
+- 开发环境禁用脱敏：设置开发模式构建
+
+---
+
+## 测试支持
+
+### 单元测试示例
+
+```typescript
+import { createLogger } from '@/main/services/logger'
+
+describe('Logger', () => {
+  it('should log with context', () => {
+    const log = createLogger('TestService')
+    // 测试逻辑...
+    expect(log).toBeDefined()
+  })
+})
+```
+
+### 集成测试
+
+```typescript
+// tests/integration/ipc-logging.test.ts
+import { loggerApi } from '@/preload/api/logger'
+
+test('Renderer logs should reach Winston', async () => {
+  // Mock Winston transport
+  // Send log via IPC
+  // Assert log appears in main process
+})
+```
+
+---
+
+## 配置参考
+
+### config.yaml 完整配置
+
+```yaml
+logging:
+  # 日志级别：error | warn | info | debug | verbose
+  level: info
+
+  # 审计日志保留天数
+  auditRetention: 30
+
+  # 应用日志保留天数
+  appRetention: 14
+```
+
+### 日志级别说明
+
+| 级别      | 使用场景       | 示例                         |
+| --------- | -------------- | ---------------------------- |
+| `error`   | 系统错误、异常 | 数据库连接失败、文件写入错误 |
+| `warn`    | 可恢复的警告   | 磁盘空间不足、重试操作       |
+| `info`    | 业务操作记录   | 用户登录、提取开始/结束      |
+| `debug`   | 技术调试信息   | API 请求参数、SQL 语句       |
+| `verbose` | 详细跟踪       | 循环迭代、中间状态           |
