feat: 实现日志与调试系统(Debug模块)

- LogLevel: 日志级别枚举 (Verbose, Debug, Info, Warning, Error, Fatal)
- LogCategory: 日志分类 (General, Rendering, Physics, Memory, Threading等)
- ILogSink: 日志输出接口
- ConsoleLogSink: 控制台输出, 支持Windows颜色
- FileLogSink: 文件日志输出
- FileWriter: 文件写入器
- Logger: 日志管理器, 支持多sink, 分类控制
- Profiler: 性能分析器
- 单元测试覆盖
