Kiro is having trouble responding right now:

### 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 26.3.1 (25D771280a)

### Expected behaviour

After logging in with Google Sign-in, the CLI should properly load my Kiro and associated profile (profileArn).
I should be able to send messages without any profile-related errors.
The /model command should display all available models.

### Actual behaviour

Kiro is having trouble responding right now:
0: Failed to send the request: An unknown error occurred: profileArn is required but no profiles are available. Please log in and select a profile.
1: An unknown error occurred: profileArn is required but no profiles are available. Please log in and select a profile.

Location:
crates/chat-cli/src/cli/chat/mod.rs:1647

Backtrace omitted. Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.

### Steps to reproduce

Open Kiro-CLI.
Log in using Google Sign-in (with the Google account that has active ).
Once logged in, send a simple message like hi.
Observe the profileArn is required but no profiles are available error.
Run the command /model and notice only "auto ----- credits" is shown.
