fix: 修复 UNIQUE 约束冲突和应用架构完善

问题修复:
- 修复项目路径 UNIQUE 约束冲突导致的创建失败问题
- 修复应用启动时数据库清理导致的卡住问题
- 修复编译错误和类型安全问题

 架构完善:
- 完善四层架构设计，符合 Tauri 开发规范
- 添加性能监控系统，支持启动时间、内存、CPU 监控
- 添加事件总线系统，实现事件驱动架构
- 增强应用状态管理，集成性能监控和事件系统

 技术优化:
- 优化数据库 PRAGMA 配置，提高数据可靠性
- 改进项目创建逻辑，自动处理路径冲突
- 添加手动清理功能，用户可主动清理无效记录
- 完善错误处理和用户反馈机制

 新增功能:
- 项目路径冲突自动处理
- 无效项目记录清理功能
- 性能监控报告生成
- 事件驱动的组件通信

 UI 改进:
- 在项目列表添加清理按钮
- 优化按钮布局和用户交互
- 增强加载状态和错误提示

 质量保证:
- 遵循 Tauri 开发规范的安全第一原则
- 实现类型安全的错误处理
- 添加详细的调试日志和状态监控
- 确保数据库操作的事务安全性

 性能优化:
- 优化数据库连接和查询性能
- 实现性能指标监控和报告
- 添加启动时间和响应时间监控
- 符合 Tauri 性能标准要求

 首页是项目列表页面
 1. 要求简洁/大方
 
+## 0.1.2 核心功能开发
+根据promptx\tauri-desktop-app-expert规定的开发规范 完成下面功能的开发
+
+1. 开发项目详情页面
+
+列表页打开后，跳转到项目详情页面
+
+1. 添加素材导入功能 业务流程如下
+导入素材->根据素材md5码检查处理结果 忽略处理成功的素材 -> 获取素材的元数据 视频/音频等数据使用ffprobe
+- 如果是视频文件 则走下面流程
+分析视频内场景->如果有镜头切换->用ffmpeg切分出来->然后检查切分出来的视频时长是否大于最大视频时长，如果大于最大视频时长进行使用ffmpeg二次切分
+- 其他文件则保存数据库 结束
