feat: 完成 C# 解析器测试、C# 转 Java 转换器和 Web API 控制器

核心功能实现: - 实现 CSharpToJavaStrategy 转换策略（包含类型映射） - 实现 CSharpToJavaConverter 转换器 - 实现 JavaCodeGenerator 代码生成器 - 实现 ConversionService 转换服务 - 实现 ConversionController Web API 控制器 - 注册 Swagger 文档和依赖注入测试覆盖: - CSharpParserTests: 8 个测试用例 - CSharpToJavaConverterTests: 5 个测试用例 - 共 13 个测试全部通过任务完成: - Task 1.2: 配置项目依赖 - Task 1.3: 建立基础架构 - Task 2.1: 实现 C# 解析器和测试 - Task 2.4: 实现 C# → Java 转换器 - Task 4.1: 创建 ASP.NET Core Web API Co-authored-by: monkeycode-ai <monkeycode-ai@chaitin.com>
