The build for `v0.37.0-alpha.3` failed on the `Create GitHub Release`
step:
https://github.com/openai/codex/actions/runs/17786866086/job/50556513221
with:
```
⚠️ GitHub release failed with status: 403
{"message":"Resource not accessible by integration","documentation_url":"https://docs.github.com/rest/releases/releases#create-a-release","status":"403"}
Skip retry — your GitHub token/PAT does not have the required permission to create a release
```
I believe I should have not introduced a top-level `permissions` for the
workflow in https://github.com/openai/codex/pull/3431 because that
affected the `permissions` for each job in the workflow.
This PR introduces `publish-npm` as its own job, which allows us to:
- consolidate all the Node.js-related steps required for publishing
- limit the reach of the `id-token: write` permission
- skip it altogether if is an alpha build
With this PR, each of `release`, `publish-npm`, and `update-branch` has
an explicit `permissions` block.
