Q autocomplete appears above Atuin output, despite atuin specified as "Disable CLIs"

### 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 15.5.0 (24F74)

### Expected behaviour

Using the Atuin CLI, I can press my up arrow to view an interactive list of previous commands run and navigate through the list using up/down arrows. Within Amazon Q I can specify "atuin" within the "Disable CLIs" section, and Amazon Q should not autocomplete/hijack the session.

### Actual behaviour

However recently Amazon Q has hijacked Atuin's functionality, whereby I can see the list of my command history, but the Amazon Q autocomplete popup appears above Atuin and intercepts any up/down key press. This occurs despite "atuin" being specified in the "Disable CLIs" section of Amazon Q's settings.

### Steps to reproduce

1. Install atuin cli and configure.
2. Specify "atuin" within Amazon Q's "Disable CLIs" settings.
3. q restart
4. Run atuin by pressing the up arrow while in a terminal session
5. A list of previous commands should appear
6. Note that Amazon Q's autocomplete also appears above the atuin output of command history, and that you cannot navigate between commands within atuin by using the up/down arrows — Amazon Q's autocomplete intercepts these key presses
