CLI shows "ctrl+enter enqueue" but "ctrl+enter" adds a line break to the prompt and "ctrl+q" is the enqueue command

### Describe the bug

https://github.com/user-attachments/assets/7df968c2-5537-4af6-96e2-bcf24f153dbe

The video shows me typing the first line, pressing ctrl + enter which enters a line break, then typing the second line, then pressing ctrl + q which enqueues the command.

### Affected version

GitHub Copilot CLI 1.0.61.

### Steps to reproduce the behavior

1. Run a command in Copilot CLI. While the command is running...
2. Type "first line" -- the instruction "ctrl+enter enqueue" should be shown
3. Press ctrl+enter -- a line break should be added to the prompt line
4. Press ctrl+q -- the prompt should be enqueued

### Expected behavior

Expected ctrl+enter to enqueue the second command

### Additional context

Windows 11 x86_64 powershell windows terminal

首先，在命令執行時，分別在 Windows PowerShell 和 Windows Terminal 中重現 Copilot CLI 的提示行為。追蹤 CLI 提示對 Ctrl+Enter 和 Ctrl+Q 的鍵盤處理，然後確認顯示的快捷鍵是否與實際將命令加入佇列的按鍵一致，並確認換行仍能如預期運作。
