Extension is Asking for Authentication for every time i run a prompt or assign a task

[umerjs]

Bug Description

The Amazon Q extension prompts for re-authentication on every prompt, task assignment, or interaction, even immediately after a successful sign-in. The authentication token/session does not persist across requests.

Steps to Reproduce

1. Open VS Code with the Amazon Q extension installed.
2. Sign in via AWS Builder ID .
3. Open the Amazon Q chat panel and submit any prompt or assign a coding task.
4. Observe that the extension immediately asks to authenticate again before processing the request.

Expected Behavior

Once authenticated, the session and OAuth tokens should persist across prompts and sessions without requiring constant re-authentication.

Actual Behavior

The extension repeatedly prompts for authentication on every prompt, interrupting workflow and making the extension unusable.
