docs: Add comprehensive configuration sections

### Added Configuration Details
- **Gemini CLI Setup**: Essential settings.json configuration
- **.geminiignore**: Performance optimization guidelines
- **MCP Tools**: Complete setup guide with links and benefits
  - Exa MCP Server for external API patterns
  - Code Index MCP for advanced code search
  - Benefits and automatic fallback explanation

### Improvements
- Organized configuration into three clear sections: Essential, Recommended, Optional
- Added installation guide links for MCP servers
- Clarified that MCP tools are completely optional
- Consistent bilingual documentation structure

+### **Recommended: .geminiignore**
+
+Optimize performance by excluding unnecessary files:
+
+```bash
+# .geminiignore (in project root)
+/dist/
+/build/
+/node_modules/

+
+### **Optional: MCP Tools** *(Enhanced Analysis)*
+
+MCP (Model Context Protocol) tools provide advanced codebase analysis. **Completely optional** - CCW works perfectly without them.
+
+#### Available MCP Servers
+
+| MCP Server | Purpose | Installation Guide |
+|------------|---------|-------------------|
+| **Exa MCP** | External API patterns & best practices | [Install Guide](https://github.com/exa-labs/exa-mcp-server) |
+| **Code Index MCP** | Advanced internal code search | [Install Guide](https://github.com/johnhuang316/code-index-mcp) |
+
+#### Benefits When Enabled
+- 📊 **Faster Analysis**: Direct codebase indexing vs manual searching
+- 🌐 **External Context**: Real-world API patterns and examples
+- 🔍 **Advanced Search**: Pattern matching and similarity detection
+- ⚡ **Automatic Fallback**: Uses traditional tools when MCP unavailable

+
+MCP (模型上下文协议) 工具提供高级代码库分析。**完全可选** - CCW 在没有它们的情况下也能完美工作。
