Amazon Q IDE-Style Completions Not Showing in Gnome Terminal on Debian Linux

### Checks

- [X] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [X] I have run `q doctor` in the affected terminal session
- [X] I have run `q restart` and replicated the issue again

### Operating system

Linux 6.6.20-aufs-1 - Debian GNU/Linux 12 (bookworm) 5785

### Expected behaviour

Amazon Q Developer CLI should provide IDE-style inline completions for commands (e.g., git, docker, npm) in the terminal as described in the documentation.

### Actual behaviour

No IDE-style completions are appearing in the terminal. Other features of Amazon Q Developer CLI are working correctly, but inline completions are not functional. I am connected via VNC
Error messages encountered:
• Xlib: extension "XInputExtension" missing on display ":5"
• Gdk-CRITICAL: gdk_window_thaw_toplevel_updates: assertion 'window->update_and_descendants_freeze_count > 0' failed

### Steps to reproduce

1. Downloaded and installed Amazon Q without **root/sudo** permissions.
2. Tested various commands like git status, docker ps, but no completions appeared.
3. other comands such as q chat, q translate all works expectedly

ソースファイルもテストのエントリーポイントも特定されていません。まず Debian Linux 上の Gnome Terminal で zsh を使って問題を再現し、q doctor と q restart を実行して、報告された XInputExtension および Gdk のエラーを調査してください。git status、docker ps、npm などのコマンドに対して IDE 形式のインライン補完が表示されれば完了です。
