autopilot-pr-merge-worker - per-PR drive-to-merge convergence loop

Writes are optional via the activation card (write: on default). autopilot-pr-review-scheduler never spawns this skill. The PR review scheduler never comments, labels, assigns, or requests reviewers.

panel-review requests a review. status/accepted is the human action flag. No accepted, no review. If status/accepted is missing on this PR and every linked issue: remove panel-review if present, do not comment, stop. Never assign. The scheduler and panel stop the same way and leave no comment.

Activation card

activation_card: on. Before any PR read or GitHub write, emit this Enter card with every field filled. Missing field -> stop.
