Describe the bug

After adding eval "$(gh copilot alias -- zsh)" to my $HOME/.zshrc, I've noticed a significant slowdown in Zsh startup time. This severely impacts the terminal user experience, as every new session takes noticeably longer to become responsive.

Environment

• gh --version: gh version 2.62.0 (2024-11-14)
• Chip: Apple M4 Pro
• Operating System: macOS 15.1.1 (24B2091)
• Terminal Emulator: iTerm2 Build 3.5.10
• Shell: zsh 5.9 (arm64-apple-darwin24.0)

Steps to reproduce the behavior

1. Add eval "$(gh copilot alias -- zsh)" to $HOME/.zshrc.
2. Observe the delay in shell startup time.
