Overview
Comment:scale-out: external NATS + multi-node fan-out (trio part 1)

events.Connect joins an external NATS so N nodes share one plane; --nats selects it (embedded stays the single-node default). Retention switched work-queue -> limits+cap: work-queue load-balanced one copy across nodes, leaving each index partial; limits fans out to per-node durables (name now carries a hashed node id) while MaxBytes/MaxAge keep disk bounded. Lease refusals surface as 503 (ops.ErrUnavailable), not 500. Verified live: two nodes on one external NATS + shared store, each folds the full store, the leased node writes while the other 503s and still folds the write cross-node.
