Hebrew text should be RTL but displayed LTR

### Describe the bug

Copilot CLI doesn't display RTL languages correctly. The problem is present for Hebrew and Arabic.
PrompT: how do you say hello in hebrew? write it in text

Response word appears flipped LTR.

In contrast Claude Code text mode writes it correctly.

### Affected version

GitHub Copilot CLI 1.0.60.

### Steps to reproduce the behavior

1. Set /model to Claude Opus 4.8
2. Type "how do you say hello in hebrew? write it in text"
3. The output displays the Hebrew characters in text in flipped order

### Expected behavior

The word Shalom should appear like this

### Additional context

_No response_

Reproduce the issue in GitHub Copilot CLI 1.0.60 using the documented /model setting and Hebrew prompt, then trace the terminal output path responsible for displaying the response. Compare Hebrew and Arabic rendering with the expected Shalom example; done means RTL text displays in the correct order without regressing ordinary text.
