Case: target lyrical, rclcpp::expand_topic_or_service_name() gains a parameter.
Note: this branch has no abi.yaml yet, so the check only runs on this pull request because the
pull request adds a verbatim copy of the rolling abi.yaml. The sticky comment and labels come from
abi-report.yaml on the default branch (workflow_run), which needs nothing on this branch.

---

This is a test pull request for the ABI checker (abi.yaml / abi-report.yaml, backed by
fujitatomoya/ros2-abi-action) and the
backport-<distro> candidate labels (#2555). It exists only for fujitatomoya to verify the
action result for one specific case, and it is closed without merging once that is done.
Maintainers: nothing to review here, please ignore this pull request.

Expected result

• abi check: failure (REP-0009 strict policy on a released distro)
• sticky comment still posted by abi-report (the publisher ignores the check conclusion): Verdict: incompatible, librclcpp.so flagged
• label ABI break added, ABI compatible absent
• no backport-* label
