Fork PRs can't access org secrets or push to GHCR, so these two
`pull_request` jobs hard-fail with no path to passing:
- `claude-md-audit` - needs `CLAUDE_CODE_OAUTH_TOKEN`
- `helm-pr-prerelease` `prerelease` job - needs `packages: write` to
push the chart
Hit this on #3449. Approving the run didn't help; the jobs ran and
failed at the privileged step. The chart-validation `lint-and-test` job
is fork-safe and stays untouched - that remains the merge gate for Helm
changes.
Gate both jobs on same-repo head:
```yaml
if: github.event.pull_request.head.repo.full_name == github.repository
```
Other PR workflows already handle forks fine: `pr_checks`
(typecheck/units/e2e/sdk-compat) falls back to anonymous DockerHub pulls
when secrets are missing.
