ddos_claude_3

### 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 6.14.0-1009-aws - Ubuntu 24.04.2 LTS

### Expected behaviour

Request would complete without terminating.

### Actual behaviour

Hi Team.
It seems your Claude models are trained on doggy data, so to speak,
or your Anthropic models have been hijacked.

Or are in reality some other models are served as Anthropic Claude

q version

> q 1.12.5

This is the output I received from using Claude 3, when it abnormally terminated,
I can see Russian and Mandarin alphabet -> Dixonix assistant cancelled

### Steps to reproduce

Execute refactoring on bash scripts few times.

### Environment

```yaml

[q-details]
version = "1.12.5"
hash = "09124c0c588530efdbde310b5110c8603c42eae3"
date = "2025-07-14T19:30:09.359298Z (10d ago)"

[system-info]
chip = "AMD EPYC 7R13 Processor"
total-cores = 1
memory = "7.56 GB"

[system-info.os.linux]
kernel_version = "6.14.0-1009-aws"
id = "ubuntu"
name = "Ubuntu"
pretty_name = "Ubuntu 24.04.2 LTS"
version_id = "24.04"
version = "24.04.2 LTS (Noble Numbat)"

[environment]
cwd = "/home/USER/projects/corretto-24-pipeline/aws-resources"
cli-path = "/home/USER/projects/corretto-24-pipeline/aws-resources"
install-method = "unknown"
in-ssh = true

[env-vars]
PATH = "/home/USER/.local/bin:/home/USER/bin:/home/USER/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/USER/.local/bin"
Q_SET_PARENT_CHECK = "1"
SHELL = "/bin/bash"
TERM = "xterm-256color"
XDG_SESSION_TYPE = "tty"
```

crates/chat-cli/src/cli/chat/mod.rs:852 から開始し、q doctor と q restart の実行後に報告された失敗を確認してください。報告された Ubuntu 環境で bash スクリプトに対するリファクタリングを数回実行して、問題を再現してください。リクエストが途中で終了せずに完了し、内部サーバーエラーが発生しなくなれば完了です。
