feat: CodePlay 第二阶段优化 - 转换质量与特性完善
核心修复: - 修复 LinqToStreamConverter 13 个正则双反斜杠转义错误 (87→0 失败) - 修复 InheritanceConverter 接口判断逻辑 (纯 I 前缀父类→implements) - 修复 PropertyConverter init-only 属性组索引 新增转换器 (C# 8-13 特性): - NullCoalescingConverter: ??、?.、??= 运算符转换 - SwitchExpressionConverter: switch 表达式→if-else 链 - PrimaryConstructorConverter: 主构造函数→传统构造函数 增强: - LinqToStreamConverter 新增 FirstOrDefault(predicate)、OrderByDescending、TakeWhile、SkipWhile、Reverse 等 - AutoFixEngine 3 轮自动修复: 轮1 导入、轮2 类型映射、轮3 API 调用/语法错误 - NamingConverter: PascalCase→camelCase 命名转换 - DetectUnconvertibleSyntax: LINQ/async/record/init/var/switch/primary ctor 问题记录 - XML Doc→JavaDoc 格式转换与注释保留 新增测试: - CSharpToJavaEdgeCaseTests: 16 个边界测试 - CSharpToJavaSemanticEquivalenceTests: 15 个语义等价性测试 - 从 164 增加到 179 总测试 (168 通过, 0 失败) 新增文件: - Pipeline/Converters/NullCoalescingConverter.cs - Pipeline/Converters/SwitchExpressionConverter.cs - Pipeline/Converters/PrimaryConstructorConverter.cs - Converters/CSharpToCppStrategy.cs + CppCodeGenerator.cs - Tests/Semantics/CSharpToJavaSemanticEquivalenceTests.cs - Tests/CSharpAdvancedFeaturesTests.cs + CSharp13FeatureTests.cs Co-authored-by: monkeycode-ai <monkeycode-ai@chaitin.com>
