High CPU usage in copilot-cli

Describe the bug

When I run copilot cli, it's taking 100% of one of the CPUs, even though the only thing the copilot is doing is waiting for a sleep operation..

Shell Wait then recheck CI status
sleep 550; cd /home/matste/ [...]

    PID USER      PRI  NI  VIRT   RES   SHR S CPU%▽MEM%   TIME+  Command
  38098 matste     20   0 15.9G  726M  149M S 27.2  2.8  0:47.95 copilot

Affected version

GitHub Copilot CLI 1.0.78.

Steps to reproduce the behavior

Ask copilot to execute any command.

Expected behavior

How hard is it to implement a text-only program that doesn't do active waiting?

Additional context

No response

まず、sleep 550 のようなコマンドを使って GitHub Copilot CLI 1.0.78 で問題を再現し、その後コマンド待機パスを調査します。待機中も CLI が応答可能なままで、CPU を消費しなくなれば完了です。同じプロセスモニターと再現コマンドを使って結果を確認してください。
