实现XY平面膨胀算法和3D体素路径规划

Browse Source 
本次提交包含三个主要改进：

1. XY平面膨胀算法（VoxelGrid.cs）
   - 实现简单迭代形态学膨胀
   - 只在水平方向（XY平面）的4邻域膨胀
   - 不在Z方向（垂直方向）膨胀
   - 符合车辆物流场景：车辆只侧面/顶部碰撞障碍物

2. 3D体素路径规划（VoxelPathFinder.cs）
   - 集成RoyT.AStar库进行3D A*路径规划
   - 支持体素网格上的路径搜索
   - 添加VoxelPathFindingTestCommand测试命令

3. UI和测试改进
   - 删除旧的包围盒测试命令（VoxelGridTestCommand.cs）
   - 更新SystemManagementView UI
   - 添加体素路径规划测试功能

核心设计原则：
- 门模型在SDF生成前被排除（留出通道空洞）
- SDF阶段只标记几何体内部为障碍物
- 安全间隙仅在XY平面膨胀阶段应用
- 避免Z方向的错误膨胀
