Title: Enable Multiple Concurrent Q CLI Sessions with Different Credentials

## Description
Currently, users are unable to run multiple Q CLI sessions with different credentials on the same machine. This limitation prevents users from simultaneously accessing their personal and company Q CLI accounts from different terminals.

## Proposed Solution
Implement a feature that allows users to run multiple concurrent Q CLI sessions, each with its own set of credentials. This will enable users to connect to their personal Q CLI account in one terminal while using company Q CLI credentials in another terminal on the same machine.

## User Story
As a Q CLI user,
I want to be able to run multiple Q CLI sessions with different credentials simultaneously on the same machine,
So that I can easily switch between my personal and company accounts without logging out and logging back in.

## Technical Considerations
- Implement a session management system to handle multiple concurrent sessions
- Ensure proper isolation of credentials and data between sessions
- Consider using environment variables or configuration files to manage different profiles

## Additional Notes
- This feature will greatly improve workflow for users who need to work with both personal and company accounts
- Consider adding a feature to easily switch between profiles within a single terminal session as a future enhancement
