Work with standard kinds

await db.events.publish({
  kind: 1,
  created_at: Math.floor(Date.now() / 1000),
  tags: [],
  content: "Hello Nostr",
});
const notes = await db.events.query({ kinds: [1], authors: [pubkey], limit: 20 });
const listener = db.events.subscribe({ kinds: [1] }, event => console.log(event));
listener.unsubscribe();

// db.pool and db.eventStore are the real Applesauce instances.

Use publishSigned for an event signed outside the SDK. Incoming and outgoing events are verified. Supply pool, eventStore, relayOptions, or a custom transport to integrate an existing Applesauce app. close() cancels subscriptions and starts resource cleanup. await closeAsync() also waits for queue shutdown and pending persistence writes; use it when durability matters. Injected pools/stores and external signers remain owned by the app.
