feat(render): 实现摄像机系统和文字渲染功能

Browse Source 
- 添加 Camera 类，支持位置、缩放、Z轴控制- 在 ModelRender 中集成摄像机投影矩阵计算
- 实现屏幕坐标到世界坐标的转换方法
- 添加默认文字渲染器和字体加载逻辑
- 在渲染面板中添加摄像机控制的鼠标手势支持
- 支持通过鼠标滚轮进行摄像机缩放操作
- 添加摄像机状态显示和调试信息渲染
- 实现多选框渲染逻辑的重构和优化
-修复坐标系变换相关的边界框计算问题
- 增加摄像机启用/禁用快捷键支持cyon 等- 添加对 Linux 和 macOS 的 LWJGL 原生库支持
- 将任务定义方式从 task 改为 tasks.register 以提高性能
- 更新部分 JavaFX 和其他图形库的版本
-优化依赖项排列顺序，增强可读性与逻辑分组
