Method recycleWorkers

src/resolution/resolver-pool.ts:298–320

* Ask every worker to close and reopen its read-only connection, and wait * for all acks. MUST be called only at the pool-idle boundary (all fanned * chunks settled, next batch not yet dispatched) — the workers close their * connections in place. Why: a long-lived reader pins WAL checkpoint

()

   * covers the rest of the run.
