fix(logger): use app.isPackaged for log dir detection and add logging docs

Previously getLogDir() only checked app.isReady(), which caused
development builds to write logs to the user data directory instead
of the local project logs/ folder. Now uses app.isPackaged to
correctly distinguish production from development environments.

Also adds comprehensive logging system documentation and a debug
utility for verifying Electron environment detection.

+
+## 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
