Case: target rolling, comment-only change. Two steps: after the first run has added the labels, a person removes backport-humble by hand and a second commit is pushed. The removed label must not come back.

---

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

Step 1 (first commit, compatible)

• abi check: success, label ABI compatible
• backport labels added: backport-lyrical, backport-kilted, backport-jazzy, backport-humble

Step 2 (manual: fujitatomoya removes backport-humble by hand, then pushes one more comment-only commit)

• abi check: success, label ABI compatible still present
• backport-lyrical, backport-kilted, backport-jazzy still present
• backport-humble not re-added (the unlabeled timeline event by a non-bot actor is honoured); the backport-label job logs Skipped label: backport-humble (removed by a maintainer)
