// compare-pr-version — CI gate helper. Compares the util's next-slot output
// against the PR's branch VERSION. Exits 0 (pass), 1 (confirmed collision),
// or 2 (util was offline — fail-open per user decision, exit 0 with warning).
// compare-pr-version — CI gate helper. Validates the PR's branch VERSION
// against the queue of other open PRs' claimed versions. Exits 0 (pass)
// or 1 (confirmed collision).
//
// Input:
// argv[2] — path to next.json (the util's JSON output)
// argv[3] — optional PR number for log lines
//
// Design note: fail-open on util error. A gstack bug must never freeze the
// merge queue. Confirmed collisions (util OK, PR version < next slot) DO block.
// merge queue. The gate enforces ONE rule: this PR must not claim the same
// version as another open PR. Lower-than-the-util's-suggestion is fine if
// the slot is unclaimed — that preserves monotonic version ordering on main
// when this PR lands ahead of higher-numbered queued PRs. The util's output
// is informational (the *recommended* slot for fresh /ship runs); the gate
// only blocks actual collisions.
