feat: 完成 CodePlay 项目初始化和核心解析器实现

- 创建 CodePlay 解决方案和 4 个项目 (Core, Web, CLI, Tests) - 实现核心数据模型 (ConversionRequest, ConversionResult, Project 等) - 实现核心接口 (IParser, IConverter, ICodeGenerator 等) - 实现基础抽象类 BaseParser - 实现 CSharpParser 解析器 (基于 Roslyn) - 添加 Microsoft.CodeAnalysis.CSharp NuGet 包 - 所有代码编译通过 Co-authored-by: monkeycode-ai <monkeycode-ai@chaitin.com>
