新增

• Native4D 管线（复旦 4DGS）：双四元数 4D 旋转 + 4D 球柱谐全支持（几何时间条件化 + 时间/视角变化颜色），资产格式 v8
• PyTorch .pth checkpoint 导入：复旦 4DGS 训练产物直接拖入（torch.save zip 格式，float32；旧 pickle 格式明确报错）
• PLY 属性自动判型：rot_4..7+scale_3 → Native4D；t/scale_t → STG 时间边缘化（含一阶速度外推）；都无 → 3DGS，无需手动选择
• 关键帧 4D：内容浏览器右键"导入 PLY 序列（关键帧 4D）"，逐帧 PLY 序列 + GPU 帧间插值（Slerp/lerp）
• .o4d v2 专属容器：打包 splat/关键帧/时间轴数据
• 4D 专用播放器编辑器：3D/4D 双击自动分流，播放/暂停/停止/步进/进度/循环/倍速全中文
• 性能设置：Nanite 精度/最大可视距离/淡出起始/排序间隔（帧），Details/蓝图/资产编辑器三处同步即时生效

已知限制（声明）

• STG 高阶运动项 motion_3..8 不求值（仅一阶线性近似，导入时日志警告）
• .pth 仅支持 torch>=1.6 zip 格式 + float32 张量
• Postshot 4D / Volinga .nvol 不支持（帧数不齐 + 格式封闭）
