移除 Client 和 Server 模块，由 Sharp.Demo 替代

Sharp.Demo 模块已经整合了 Client 和 Server 的所有功能，
并采用了最佳实践（Quick Start API、标准 DI、Result<T> 模式等），
因此 Client 和 Server 模块已不再需要。

变更内容：
- 从解决方案中移除 Client 和 Server 项目
- 更新 CLAUDE.md 文档（根目录和 src/Sharp/）
- 更新项目结构说明，明确 Sharp.Demo 为综合演示应用
- 更新构建和运行命令，指向 Sharp.Demo
- 更新依赖关系说明

Sharp.Demo 优势：
- 使用 Quick Start API 简化配置
- 标准依赖注入（移除 Global 容器依赖）
- Result<T> 模式演示
- IApplicationState 应用状态管理
- 完整的开发者工具集成（F10/F11/F12）
- 交互式模块演示（17+ 功能点）
