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

Browse Source 
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
