chore(release): v0.1.1 USD文件初步校验

原因:记录 L20 USD 初步校验、严格浮动覆盖层、受限动力学回放及 HDF5 交付契约,包版本更新为 0.1.1。

验证:68 项 CPU/USD 回归测试通过,Ruff/format 与暂存 diff 检查通过;已核验单环境 small 2x480、合成 HDF5 2x960 步明确 PASS。独立暂存审查未发现问题。完整 pre-commit 因模块缺失未执行,干净环境安装未验证。

兼容性:Cartpole 及任务 ID 不变,原始 USD/URDF 未改;旧 prepared 覆盖层需重新生成。仅合成轨迹初步校验,不代表真实专家回放、训练或硬件验收。

Run headless with an external timeout. This legacy topology diagnostic deliberately
performs no dynamic experiment (see track_l20.py for the experimental path). Create a disposable
