+fix(ci): hand the cross-repo token to github-script instead of requiring @actions/github
+
+Release-nothing: touches `.github/workflows/cross-repo-issue-closer.yml` only.
+
+`require('@actions/github')` is not resolvable from a github-script `script:`
+block — the action bundles its dependencies, so the call fails at runtime with
+`MODULE_NOT_FOUND`. The token is now handed to the action itself
+(`github-token:`), which makes the injected `github` client the cross-repo one,
+with `secrets.GITHUB_TOKEN` as the fallback so the report path can still
+comment on the pull request when no cross-repo credential is configured.
+
+Observed in objectui, whose copy of this workflow reached that line first. Its
+run also confirmed the credential logging added alongside works, printing
+`CROSS_REPO_ISSUE_TOKEN: configured` before failing at the require.
+
+This supersedes #4573, which renamed the second client without removing it —
+the rename fixed the identifier collision that aborted parsing, and only then
+did the run get far enough to hit the unresolvable module. Three failures in
+three consecutive runs, each one further down the same script: parse, resolve,
+then (expected next) the API calls themselves.
