- 修改记录存储格式为 [4B len][8B offset][4B CRC][16B UUID][data] - 修复 TopicProcessor 中 WaitGroup 使用错误导致 handler 不执行的问题 - 修复写入保护逻辑，避免 dirtyOffset=-1 时误判为写入中 - 添加统计信息定期持久化功能 - 改进 UTF-8 字符截断处理，防止 CJK 字符乱码 - 优化 Web UI：显示人类可读的文件大小，支持点击外部关闭弹窗 - 重构示例代码，添加 webui 和 webui_integration 示例 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
