feat: 完成剩余 P1/P2 优化任务

新增功能: ✅ 代码格式化集成 (CodeFormatter.cs) - 支持 C# (dotnet format) - 支持 Java (google-java-format) - 支持 C++ (clang-format) - 自动检测格式化工具可用性 ✅ WebSocket 实时推送 (ConversionHub.cs) - SignalR Hub 实现 - 进度组管理 - 实时转换进度推送 ✅ Python 语言支持 - PythonParser.cs: Python 代码解析 - PythonToCSharpConverter.cs: Python→C# 转换 - 支持 class/def/import 解析测试结果: 42 个测试 (41 通过，1 跳过) ✅ 新增文件: - CodePlay.Core/Services/CodeFormatter.cs - CodePlay.WebAPI/Hubs/ConversionHub.cs - CodePlay.Core/Parsers/PythonParser.cs - CodePlay.Core/Converters/PythonToCSharpConverter.cs 延后任务: ⏸️ 差异对比功能：需要 Monaco Diff Editor 深度配置 ⏸️ 前端编译：Vite + Monaco 配置复杂，需专项处理 Co-authored-by: monkeycode-ai <monkeycode-ai@chaitin.com>
