publishToRelays(urls, ev, opts) publisht signiertes event parallel zu
allen relays, mit retries + exponential backoff + timeout pro versuch.
retour: { ok: string[], failed: string[] }. default-pool via
applesauce-relay 2.x (new RelayPool()); publishFn via dependency-
injection für tests. checkExisting(slug, pubkey, urls) fragt je relay
nach kind:30023 mit #d-filter ab — true wenn irgendeiner matcht.
timer-leaks vermieden per clearTimeout in publishOne + im mock-test.
3 tests grün.
