refactor: 重构项目结构，优化代码组织与文件布局 

将源代码从Extra2D/src迁移到src目录，统一文件路径
更新xmake构建配置以适配新路径
清理冗余代码文件，合并重复实现
调整头文件包含路径，确保编译通过
优化过渡动画场景实现，移除不必要的动画效果

使用 Extra2D 游戏引擎开发的游戏项目。
## 支持平台
- MinGW (Windows)
- Nintendo Switch
## 项目结构

├── src/ # 源代码目录
│ └── main.cpp # 主程序入口
├── romfs/ # 资源文件目录

│ ├── images/ # 图片资源
│ └── audio/ # 音频资源
├── Extra2D/ # 引擎源码

```
## 构建说明
### 前置要求
- [xmake](https://xmake.io/) 构建工具
- MinGW-w64 工具链 (Windows) 或 devkitPro (Switch)
### 构建步骤
#### Windows 平台
```bash
# 配置项目
xmake config -p mingw
# 构建项目
xmake build
# 运行项目
xmake run {self.project_name}
```
#### Nintendo Switch 平台
```bash
# 配置项目
xmake config -p switch
# 构建项目
xmake build
# 生成的 NRO 文件位于 build/switch/ 目录
```
## 资源文件
请将游戏所需的资源文件放入 `romfs/assets/` 目录：
- `images/` - 图片资源（PNG, JPG 等）
- `audio/` - 音频资源（WAV, OGG 等）
- `font.ttf` - 字体文件（需要手动添加）
