description	Review and decide a Station's Checkpoint — approve to advance the Run, or request changes to route rework as drift

The Run is holding at a Station Checkpoint. Surface the Station's result and the Reviewers' findings to the user, then record the decision with darkrun_checkpoint_decide:

• approved: true — the Checkpoint passes, the artifact locks, the manager advances.
• approved: false with feedback — the manager holds the Station and routes the rework back through the feedback track.

Then /darkrun:darkrun-resume to continue.
