/**
 * `pnpm agent:ready` — flip plan-issue Issues from `blocked` → `ready` after
 * the intention plan is on `main` (OPS17 Passo 6). Idempotent per issue.
 *
 *   pnpm agent:ready -- --issue 292
 *   pnpm agent:ready -- --issue 292,293
 *
 * Fail-closed via `canPromotePlanIssue`: open + `blocked` + `docs/plans/` link,
 * and not `needs:consent` / `requirements-changed` / `in-progress`|`done`|`in-prod`.
 * Idempotent skip when already `ready`. Product-blocked Issues without a plan
 * link stay for human triage.
