Enhance GitHubStatsAnalyzer with code change statistics and improved output formatting

- Added accurate line counting for code changes, distinguishing between all files and code files only.
- Introduced new statistics for code additions, deletions, and net change, enhancing the analysis detail.
- Updated output formatting in text, JSON, and CSV to include code change statistics, improving clarity and usability.
- Refactored the analyzer to handle commit file details, allowing for more granular tracking of changes per file.
- Enhanced tests to validate new features and ensure accurate reporting of code statistics.

 ## 📝 Notes
 
 - The program analyzes all repositories including forks, but only counts the user's own contributions
+- **Highly Accurate Line Counting**: Unlike other tools that estimate based on file size, our analyzer precisely counts actual code lines by analyzing commit data
 - GitHub API has rate limits, so analyzing users with many repositories might take time
-- Lines of code are estimated based on byte count (approximation)
 - Some languages are excluded by default to avoid skewing statistics (use `--include-all` to include them)
 - Log files are stored in the `logs` directory
 - Basic access mode is suitable for quick analysis of public repositories

 ## 📝 注意事项
 
 - 程序分析所有仓库包括 fork 的仓库，但只统计用户自己的贡献
+- **高精度代码行统计**：与其他基于文件大小进行估算的工具不同，我们的分析器通过分析提交数据精确计算实际代码行数
 - GitHub API 有速率限制，因此分析拥有许多仓库的用户可能需要一些时间
-- 代码行数是基于字节数的估计（近似值）
 - 默认情况下排除某些语言以避免统计偏差（使用 `--include-all` 选项可包含所有语言）
 - 日志文件存储在 `logs` 目录中
 - 基础访问模式适合快速分析公开仓库
