name: Label documentation PR

# SECURITY: this workflow runs in the privileged `pull_request_target` context
# but does NOT check out PR-controlled code. It only adds the `documentation`
# label using the GITHUB_TOKEN. The actual documentation build is intentionally
# split out into `docs_build.yaml`, which runs in the fork-isolated
# `pull_request` context.
