Ctrl+G fails to open $EDITOR during ask_user (clarifying question) prompts

Describe the bug

When Copilot CLI asks a clarifying question via the  ask_user  tool (multiple-choice or freeform), pressing Ctrl+G does not open  $EDITOR  as it normally does in the main input box. Instead, the keypress causes the question to be registered as "skipped."

Affected version

1.0.71

Steps to reproduce the behavior

1. Have Copilot CLI ask a clarifying question (e.g., via  ask_user ).
2. While the question prompt is active, press Ctrl+G.
3. Observe: editor does not open; the question is immediately marked as skipped.

Expected behavior

Ctrl+G should open  $EDITOR  for composing a response to the question, same as it does in the normal chat input box.

Additional context

OS: macOS (Darwin)
$EDITOR: NeoVim

ask_user プロンプトの入力処理から始め、Ctrl+G の動作を、issue に記載されているメイン入力ボックスの経路と比較してください。$EDITOR に NeoVim を設定した macOS で再現してください。Ctrl+G によって質問がスキップ済みとしてマークされるのではなく、回答用のエディタが開けば完了です。
