feat: 添加 VEO3 场景写作工具并优化文件处理逻辑

- 创建 VEO3SceneWriterTool 页面组件，集成聊天界面和文件选择功能
- 添加 veo3SceneWriterService 服务层，封装与 Rust 后端的通信逻辑
- 实现 Tauri 命令支持，调用 veo3-scene-writer crate
- 更新工具数据配置，添加 VEO3 场景写作工具
- 优化文件处理逻辑：JSON/TXT 文件读取内容作为消息，图片文件作为附件
- 支持多种文本格式：.json, .txt, .md, .yaml, .yml, .toml
- 提供专业的影视场景提示词生成功能
