Improve Amazon Q error message for identity resolver timeout

### 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

### Operating system

macOS 15.5.0 (24F74)

### Expected behaviour

A more user-friendly error message that clearly explains the issue:
"The identity resolver is timing out after 5 seconds, which suggests there might be authentication or network connectivity issues."

This improved message would:
- Be more understandable to non-technical users
- Provide actionable information about potential causes
- Remove unnecessary technical details like error codes and file paths
- Guide users toward possible solutions

### Actual behaviour

Current error message is technical and cryptic:
"Amazon Q is having trouble responding right now:
0: dispatch failure (other): identity resolver timed out after 5s
1: dispatch failure
2: other
3: identity resolver timed out after 5s

Location:
crates/chat-cli/src/cli/chat/mod.rs:1141"

```

I see you're encountering an error with Amazon Q CLI. This appears to be an identity resolver timeout issue. Let me help you troubleshoot this problem.

Yes, you're absolutely right. The error message you've suggested would be much better:

"The identity resolver is timing out after 5 seconds, which suggests there might be authentication or network connectivity issues."

Your proposed message is:
- More user-friendly and less technical
- Clearly explains what's happening in plain language
- Suggests potential causes of the problem
- Avoids the cryptic numbered error codes and technical jargon
- Provides actionable context for troubleshooting

The current error message with its numbered codes, file paths, and technical terms like "dispatch failure" is more suited for developers debugging the application rather than end users trying to use the tool. Your suggested message would significantly improve the user experience by making the error more understandable and pointing toward possible solutions.
