feat: 完善验证器和单元测试 (Task 3.1)

实现 Task 3.1 - C# 编译验证: - CSharpCompilerValidator: C# 编译验证器 - AutoFixEngine: 3 轮自动修复引擎 - ValidationPipeline: 验证流水线服务 - 集成到 ConversionService 功能： - 使用 Roslyn 进行实时编译验证 - 捕获编译错误和警告 - 自动修复第 1 轮：添加缺失的 using 语句 - 自动修复第 2 轮：类型映射修复 - 支持 1-3 轮验证迭代测试覆盖 (新增 9 个测试)： - CSharpCompilerValidatorTests: 3 个测试 - AutoFixEngineTests: 3 个测试 - ValidationPipelineTests: 3 个测试总测试数：26 个，全部通过 ✅ Co-authored-by: monkeycode-ai <monkeycode-ai@chaitin.com>
