Claude 6060c50f79 perf(cli): keep a warm connection pool to the top relays during the crawl ...

The client's relay pool reconciles open sockets to the relays that active
subscriptions currently need, so between-round gaps (routing + contactsOf scans
> ~300ms) and niche-relay churn dropped connections we reuse every round, then
reconnected them — a TCP+TLS+WS handshake each time.

Hold a persistent do-nothing subscription (WARM_SUB_ID) open to the busiest
WARM_POOL_SIZE(20) live relays, refreshed to the current top set at each round
start (same subId → just updates the desired-relay set) and closed when the
crawl finishes. Its filter matches an impossible event id, so the relay EOSEs
immediately and streams nothing — it only keeps the socket warm.
