TRELLIS2 Official Subs Component Probe

继续严格沿官方 TRELLIS.2 latent / subs 路线，但把单节点匹配升级为 coarse occupancy component 匹配。核心结论是：官方 subs 经过连通组件聚合后，GT mean IoU 从 8.1e-05 提升到 0.1553，说明它们更像“part-support field”而不是可直接监督的语义 part 节点。

这一步不再强迫 GT part 对齐单个 octree cell，而是在固定 level 上把相邻 occupied cells 聚成 connected components，再从 component 反推 bbox 与粗结构树。结果还不够论文级，但方向已经明显更合理：level-2 上自动找到 2 个组件，成功对齐 2 个 GT parts，mean IoU 提升到 0.1553。
