/ask feature un-useable due to answer being in a cramped text box

### Describe the feature or problem you'd like to solve

When you use the /ask feature and the answer comes back, it only shows a few lines, leaving you to scroll through it trying to comprehend an answer which may contain details and code snippets. Its too much info to only read a few lines at a time.

### Proposed solution

Configure the /ask feature so a user can actually read the answer instead of having it constrained inside a small few lines text control. Yes you can scroll, but scrolling a few lines at a time when the answer may contain code snippets makes it unusable.

### Example prompts or workflows

_No response_

### Additional context

_No response_

Start at the /ask feature's answer-display entry point and trace how returned text is rendered in the terminal. Confirm the current constrained text control, then verify that long answers and code snippets are readable without being limited to only a few lines.
