V1 broken - GET /user - 403 (HttpError: Resource not accessible by integration - https://docs.github.com/rest/users/users#get-the-authenticated-user)

**Describe the bug**
After upgrading from Beta to V1, I'm getting this error and no comments are being posted (though the code review still runs and takes minutes and spends tokens ).

```

**Expected behavior**
The PR comments should be working and it should not be hitting GET /user, which fails for the GitHub App token (that endpoint is blocked for App/GITHUB_TOKEN auth).

**Workflow yml file**
Above

**API Provider**

[X] Anthropic First-Party API (default)
[ ] AWS Bedrock
[ ] GCP Vertex

**Additional context**
This may be the same as https://github.com/anthropics/claude-code-action/issues/9 but that was marked as "compelted" today with no indication of what happened. Is this in V1, in a future version? What is the workaround? Should I (and anyone facing this) return to the Beta? This seems like a major blocker.

Claude.ai suggested I change
```yml
permissions:
pull-requests: read
```
to
```yml
permissions:
pull-requests: write
```
but that didn't change anything, unsurprisingly since it's fetching GET /user

ChatGPT suggested this as a workaround:
```yml
env:
# Avoid the /user call by pre-setting a bot identity
GIT_AUTHOR_NAME: github-actions[bot]
GIT_AUTHOR_EMAIL: 41898282+github-actions[bot]@users.noreply.github.com
GIT_COMMITTER_NAME: github-actions[bot]
GIT_COMMITTER_EMAIL: 41898282+github-actions[bot]@users.noreply.github.com
```
which I will try, but this seems very hacky.

Any workarounds from the Anthropic team?
