fix(assets): stabilize L20 fixed-base PhysX preview

原因:保存 L20 资产、固定基座、地面光照、相邻碰撞过滤和拇指受限驱动,
修正过短时间轴;USD 依赖通过 Git LFS 管理,转换元数据移除个人路径。
包含 GUI 有限步数拇指回归入口与验证记录。

验证:用户 Isaac Sim 6.0.1 GUI 中等价回归代码完成 3840 物理步,PASS。
提交前 pxr Stage.Open/ComputeAllDependencies:10 层、0 未解析依赖、0 组合错误。
Python AST 语法、git diff --cached --check、LFS 指针哈希与 git lfs fsck 均 PASS。
pre-commit run --all-files:BLOCKED,命令未安装;仓库许可证模板也缺失。
Isaac Lab 任务发现/训练 E2E NOT_RUN:当前资产尚未接入任务,不启动额外仿真。

兼容性:包版本维持 0.1.0,现有 Cartpole 配置未改变;需要 Git LFS。
armature 为未标定数值参数;mimic 耦合、其他手指大动作、reset/replay 和
长时间 RTX 渲染资源耗尽仍未验收。本提交不表示训练或发布就绪。

Fixed
^^^^^
* Configure the L20 PhysX preview with a world-fixed articulation root, ground,
lighting, and 240 Hz physics to prevent the observed 60 Hz instability.
Add a bounded editor smoke script; Isaac Lab task integration is not included.
* Stabilize L20 thumb target reversals with bounded position drives and numerical
armature, explicitly filter adjacent links, and correct the preview timeline.
Remove persisted editor render nodes; long-duration RTX stability remains unverified.
