feat: implement xiaohongshu automation with MCP server

Complete implementation of xiaohongshu (Little Red Book) automation system:

### Core Features:
- **QR Code Login**: Automated login with cookie persistence
- **Content Publishing**: Post text, images with AI-powered descriptions
- **Browser Management**: Headless Chrome automation via go-rod
- **Cookie Persistence**: Session management for login state
- **MCP Server**: Model Context Protocol integration for Claude

### Technical Components:
- go-rod browser automation with stealth mode
- MCP server for Claude Code integration
- Cookie-based session management
- Robust error handling and logging
- Cross-platform compatibility

### API Endpoints:
- Login status checking and QR code authentication
- Content publishing with image upload support
- Navigation and page interaction utilities

This provides a complete foundation for xiaohongshu automation
with proper session management and MCP integration.
