Pull request overview
This PR adjusts the Jetson Docker build to avoid dependency-resolution failures when the Jetson AI Lab index lags behind PyPI for the xgrammar package, while keeping the LMDeploy wheel installation (and its CUDA/Torch ecosystem) pinned to the Jetson AI Lab index.
Changes:
- Add a Dockerfile note explaining the split-index installation strategy for
xgrammarvs. LMDeploy wheel dependencies. - Preinstall
xgrammar==0.1.33from PyPI (without dependencies), then install the LMDeploy wheel from the Jetson AI Lab index.

Motivation
The Jetson AI Lab package index may lag xgrammar releases, which can prevent the Jetson Docker image from resolving LMDeploy's xgrammar dependency.
