Q keeps trying to call the AWS CLI after credentials have expired

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 14.7.6 (23H626)

### Expected behaviour

After Q gets an error due to expired credentials (ExpiredTokenException, RequestExpired, etc), it should stop trying and prompt me to sign in again.

### Actual behaviour

After Q gets an error due to expired credentials (ExpiredTokenException, RequestExpired, etc), it keeps making more CLI calls to try and get more information another way.

### Steps to reproduce

1. Sign in to AWS with a token that will expire in one hour.
2. Use Q for more than one hour.

### Environment

```yaml

Riproduci il problema effettuando l’accesso con credenziali che scadono e usando poi Q per più di un’ora; usa q doctor e q restart come indicato nel report. Traccia la gestione di ExpiredTokenException e RequestExpired dopo le chiamate AWS CLI. Il lavoro è completato quando Q smette di effettuare ulteriori chiamate e chiede all’utente di effettuare nuovamente l’accesso.
