Apply the patch after review

The patch is available in the workflow run artifacts:

**Workflow Run:** [View run details and download patch artifact](https://github.com/githubnext/tsb/actions/runs/28645236978)

```sh
# Download the artifact from the workflow run
gh run download 28645236978 -n agent -D /tmp/agent-28645236978

# Apply the patch to the pull request branch
git fetch origin autoloop/build-tsb-pandas-typescript-migration
git checkout autoloop/build-tsb-pandas-typescript-migration
git am --3way /tmp/agent-28645236978/aw-autoloop-build-tsb-pandas-typescript-migration.patch
git push origin autoloop/build-tsb-pandas-typescript-migration
```

To route changes like this to a review issue instead of blocking, configure `protected-files: fallback-to-issue` in your workflow configuration.

首先检查 pull request #363 和受保护的文件 .github/workflows/ci.yml。下载 workflow run 28645236978 的 artifact 以检查被阻止的 patch，然后在更新 pull request 分支之前确定这些更改是否可接受。完成的标准是已审查受保护文件的更改，并且 pull request 已得到处理。
