feat: 完成文件导入功能和Book模型扩展
## 新增功能 - EPUB文件导入功能:支持文件选择、解析和存储 - 文件重复检测:避免重复导入同一文件 - 导入状态反馈:成功/失败消息提示 ## 模型扩展 - Book模型新增多作者支持(authors字段) - 新增章节数统计(chapterCount字段) - 新增语言标识(language字段) - 新增EPUB标识符(identifier字段) - 优化TypeAdapter序列化支持 ## 服务优化 - 新增EpubParserService:EPUB文件解析服务 - 改进DatabaseService:错误处理和数据迁移 - 优化BookRepository:调试日志和错误追踪 ## 依赖更新 - 新增epubx ^4.0.0:EPUB电子书解析库 - 更新pubspec.lock:同步依赖版本 ## UI改进 - AppHeader组件集成完整导入功能 - SafeArea适配:避免系统状态栏重叠 - 优化测试数据结构 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
