Integrate NDK nip66MonitorRelays when PR #387 lands

[alltheseas]

TLDR

I added an outbox improvement PR to NDK that

1. improves algo event coverage by ~~ 25% by utilizing thompson learning
2. decreases result loading time 40%-50% by fetching NIP-66 relay liveness results

More details

NDK PR #387 adds NIP-66 relay filtering at the NDK connection level — filtering dead relays before WebSocket connection establishment (~45% faster loading in their benchmarks).

Once it lands, we can pass nip66MonitorRelays to the NDK constructor in src/lib/ndk.ts:

const ndk = new NDK({
  explicitRelayUrls: [...RELAYS.DEFAULT],
  nip66MonitorRelays: ['wss://relaypag.es', 'wss://relay.nostr.watch', 'wss://monitorlizard.nostr1.com'],
});

This is independent from our application-level NIP-66 integration (#136) which handles NIP-50 relay discovery and search-time dead relay filtering. The NDK layer would provide WebSocket connection savings on top.

Closing as not planned. Stability and performance improvements are the priority right now. We're not adding new NIP kind renderings until the existing search and UI are solid.
