feat: 优化社区动态新闻分页和预加载策略

## 主要改动

### 1. 修复分页显示问题
- 修复总页数计算错误（使用服务端 total 而非缓存 cachedCount）
- 修复目标页数据检查逻辑（排除 null 占位符）

### 2. 实现请求拆分策略 (Critical Fix)
- 将合并请求（per_page: 15）拆分为单页循环请求（per_page: 5）
- 解决后端无法处理动态 per_page 导致返回空数据的问题
- 后台预加载和显示 loading 两个场景均已拆分

### 3. 优化智能预加载逻辑
- 连续翻页（上/下页）：预加载前后各 2 页
- 跳转翻页（点页码）：只加载当前页
- 目标页已缓存时立即切换，后台静默预加载其他页

### 4. Redux 状态管理优化
- 添加 pageSize 参数用于正确计算索引
- 重写 reducer 插入逻辑（append/replace/jump 三种模式）
- 只在 append 模式去重，避免替换和跳页时数据丢失
- 修复 selector 计算有效数量（排除 null）

### 5. 修复 React Hook 规则违规
- 将所有 useColorModeValue 移至组件顶层
- 添加缺失的 HStack 导入

## 影响范围
- 仅影响社区页面动态新闻分页功能
- 无后端变更，向后兼容

 ## Architecture
 
 ### Frontend Structure
-- `src/layouts/` - Main layout components (Admin, Auth, Home)
-- `src/views/` - Page components organized by feature (Dashboard, Company, Community, etc.)
-- `src/components/` - Reusable UI components (Charts, Cards, Buttons, etc.)
-- `src/theme/` - Chakra UI theme customization
-- `src/routes.js` - Application routing configuration
-- `src/contexts/` - React context providers
-- `src/services/` - API service layer
+- **src/App.js** - Main application entry with route definitions (routing moved from src/routes.js)
+- **src/layouts/** - Layout wrappers (Auth, Home, MainLayout)
+- **src/views/** - Page components (Community, Company, TradingSimulation, etc.)
+- **src/components/** - Reusable UI components
+- **src/contexts/** - React contexts (AuthContext, NotificationContext, IndustryContext)
+- **src/store/** - Redux store with slices (posthogSlice, etc.)
+- **src/services/** - API service layer
+- **src/theme/** - Chakra UI theme customization
+- **src/mocks/** - MSW (Mock Service Worker) handlers for development
+  - src/mocks/handlers/ - Request handlers by domain
+  - src/mocks/data/ - Mock data files
+  - src/mocks/browser.js - MSW browser setup
 
 ### Backend Structure
-- `app_2.py` - Main Flask application with routes and business logic
-- `simulation_background_processor.py` - Background data processing service
-- `wechat_pay.py` / `wechat_pay_config.py` - Payment integration
-- `tdays.csv` - Trading days data
+- **app.py / app_2.py** - Main Flask application with routes, authentication, and business logic
+- **simulation_background_processor.py** - Background processor for trading simulations
+- **wechat_pay.py / wechat_pay_config.py** - WeChat payment integration
+- **concept_api.py** - API for concept/industry analysis
+- **tdays.csv** - Trading days calendar data (loaded into memory at startup)
 
 ### Key Integrations
-- ClickHouse for high-performance analytics queries
-- Celery + Redis for background task processing
-- Flask-SocketIO for real-time data updates
-- Tencent Cloud services (SMS, etc.)
-- WeChat Pay integration
+- **ClickHouse** - High-performance analytics queries
+- **Celery + Redis** - Background task processing
+- **Flask-SocketIO** - Real-time data updates via WebSocket
+- **Tencent Cloud** - SMS services
+- **WeChat Pay** - Payment processing
+- **PostHog** - Analytics (initialized in Redux)
+- **MSW** - API mocking for development/testing
+
+### Routing & Code Splitting
+- Routing is defined in **src/App.js** (not src/routes.js - that file is deprecated)
+- Heavy components use React.lazy() for code splitting (Community, TradingSimulation, etc.)
+- Protected routes use ProtectedRoute and ProtectedRouteRedirect components
 
 ## Configuration
 
-### Proxy Setup
-The React dev server proxies API calls to `http://localhost:5001` (see package.json).
-
 ### Environment Files
-- `.env` - Environment variables for both frontend and backend
+Multiple environment configurations available:
+- **.env.mock** - Mock data mode (default for `npm start`)
+- **.env.local** - Real backend connection
+- **.env.development** - Development environment
+- **.env.test** - Test environment
 
-### Build Process
-The build process includes custom Gulp tasks that add Creative Tim license headers to JS, CSS, and HTML files.
+### Build Configuration (craco.config.js)
+- **Webpack caching**: Filesystem cache for faster rebuilds (50-80% improvement)
+- **Code splitting**: Aggressive chunk splitting by library (react-vendor, charts-lib, chakra-ui, antd-lib, three-lib, etc.)
+- **Path aliases**: `@` → src/, `@components` → src/components/, `@views` → src/views/, `@assets` → src/assets/, `@contexts` → src/contexts/
+- **Optimizations**: ESLint plugin removed from build for speed, Babel caching enabled, moment locale stripping
+- **Source maps**: Disabled in production, eval-cheap-module-source-map in development
+- **Dev server proxy**: `/api` requests proxy to http://49.232.185.254:5001
 
-### Styling Architecture
-- Tailwind CSS for utility classes
-- Custom Chakra UI theme with extended color palette
-- Component-specific SCSS files in `src/assets/scss/`
+### Important Build Notes
+- Uses NODE_OPTIONS='--openssl-legacy-provider --max_old_space_size=4096' for Node compatibility
+- Gulp task adds Creative Tim license headers post-build
+- Bundle analyzer available via `ANALYZE=true npm run build:analyze`
+- Pre-build: kills any process on port 3000
 
 ## Testing
-- React Testing Library setup for frontend components
-- Test command: `npm test`
+- **React Testing Library** for component tests
+- **MSW** (Mock Service Worker) for API mocking during tests
+- Run tests: `npm test`
 
 ## Deployment
-- Build: `npm run build`
-- Deploy: `npm run deploy` (builds the project)
+- Deployment scripts in **scripts/** directory
+- Build output processed by Gulp for licensing
+- Supports rollback via scripts/rollback-from-local.sh
