how to handle a forvever reader for a client unless the client is closed by program

```
client, err := pulsar.NewClient(pulsar.ClientOptions{URL: "pulsar://localhost:6650"})
if err != nil {
log.Fatal(err)
}

defer client.Close()

reader, err := client.CreateReader(pulsar.ReaderOptions{
Topic: "topic-1",
StartMessageID: pulsar.EarliestMessageID(),
})
if err != nil {
log.Fatal(err)
}
defer reader.Close()

for reader.HasNext() {
msg, err := reader.Next(context.Background())
if err != nil {
log.Fatal(err)
}

fmt.Printf("Received message msgId: %#v -- content: '%s'\n",
msg.ID(), string(msg.Payload()))
}
```
This is example the doc shows. I‘m consufed with how to handle the reader. If a connection is aborted(not program close it), would the reader break？

Start with the ReaderOptions example in the issue and inspect the reader lifecycle around HasNext, Next, and Close. Confirm what happens after an aborted connection, then document the expected behavior and recovery path; no file or test is named in the issue.
