/**
 * Shared SimplePool for all relay connections in the app.
 *
 * Every service previously created its own SimplePool (client.service,
 * graph-query.service, EventBrowserTab, RecoveryTab), and each pool opens a
 * separate WebSocket per relay. With multiple pools alive at once, one client
 * could hold many connections to the same relay (main pool + graph pool +
 * tab pools + cache relay), tripping per-IP connection caps on personal
 * relays. A single shared pool guarantees exactly one connection per relay
 * across the whole app.
 *
 * Note: `trackRelays` is enabled so `seenOn` metadata works for the main
 * client service.
