Fixes landing script dequeues failing because the GraphQL mutation sent pullRequestId where GitHub expects id, so merge-pr refused PRs it should have pulled from the merge queue.
The fake gh test harness now rejects the wrong input field for dequeue and auto-merge disable, matching GitHub's real API behavior.
Adds a benchmark slice descriptor covering the dequeue input field.
Confidence Score: 5/5
The PR appears safe to merge; no actionable issues were found.
