### Describe the bug

Aucun fichier source, test ou étape de reproduction n’est nommé. Commencez par confirmer que cela relève de github/copilot-cli et reproduisez le comportement de forte utilisation du CPU dans Copilot CLI v1.0.65, en le comparant à v1.0.61 tout en examinant les logs fournis. Le travail sera considéré comme terminé lorsque la régression aura été identifiée et corrigée, avec la vérification que la commande de review ne reste plus inactive avec une utilisation élevée du CPU.
