refactor: 重构纹理图集工具，实现浏览器端实时处理

将合图处理从服务端迁移到浏览器端，使用 Web Worker 实现高性能打包算法，新增三栏布局界面和精灵动画预览功能

- 新增 atlasStore 状态管理，实现文件、配置、结果的统一管理
- 新增 atlas-packer 打包算法库（MaxRects/Shelf），支持浏览器端快速合图
- 新增 atlas-worker Web Worker，实现异步打包处理避免阻塞 UI
- 新增三栏布局组件：FileListPanel、CanvasPreview、AtlasConfigPanel
- 新增 AnimationPreviewDialog 支持精灵动画帧预览和帧率控制
- 优化所有工具页面的响应式布局和交互体验
