/**
* `pnpm agent:claim` — claim the next trackable issue for this agent run.
*
* Queue: open issues labeled `ready`, filtered to UNBLOCKED (every frontmatter
* `depends` id is closed or labeled `done`/`in-prod`), ordered by `prio:P0..P3`
* then oldest first. `--dry-run` prints the queue without claiming.
*
* Lock otimista: re-reads the issue right before flipping labels, refuses if
* someone else already took it (`in-progress` present / `ready` gone), then
* swaps ready→in-progress and leaves a claim comment with the run timestamp.
*
* Output: the brief on stdout (issue, id, priority, plan/spec body) — the
* agent reads it and starts; it does NOT create the branch (Cursor worktrees
* own that) and it never merges anywhere. PRs go `--base stage`.
