feat: 实现 Java 完整解析器和不可转换语法处理 (Task 2.2, 2.8)

Task 2.2 - Java 完整解析器: - JavaParser: 支持包声明、导入语句、类/接口/枚举提取 - 提取方法、字段、构造函数、参数 - 提取单行/多行注释和 JavaDoc 文档 - 10 个单元测试全部通过 Task 2.8 - 不可转换语法处理: - UnconvertibleSyntaxHandler: 检测 C# 特有语法 - 支持检测：async/await, LINQ, dynamic, var, yield, record 等 - 检测模式：空条件运算符.?，空合并??, 字符串插值$等 - 转换可行性评估：置信度评分和努力程度估算 - 自动生成 TODO 注释标记 - 3 个单元测试通过 Task 4.2 - API 认证: - AuthController: JWT 认证端点 (login, refresh, me) - Program.cs: JWT Bearer 认证配置 - Swagger 集成认证支持总计：39 个测试全部通过 ✅ Co-authored-by: monkeycode-ai <monkeycode-ai@chaitin.com>
