## Description

Test that `createPubSub` works correctly when configured with the Redis event target. This is an integration test that verifies the core factory and the adapter work together:

```ts
const pubsub = createPubSub<MyEventMap>({
  eventTarget: createRedisEventTarget({ publishClient, subscribeClient }),
});
```

This tests the full round-trip: publish through createPubSub → dispatch through Redis → receive on the other side.

## Acceptance Criteria

- [ ] Integration test: publish via `createPubSub` + Redis event target
- [ ] Integration test: subscribe via `createPubSub` + Redis event target
- [ ] Integration test: full envelope round-trip (type, id, payload)
- [ ] Integration test: topic scoping works with `type:id` through Redis
- [ ] Integration test: channel prefix is correctly applied when configured
