Q chat hangs when file content contains auth tokens

### 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

macOS 15.4.1 (24E263)

### Expected behaviour

Q chat should properly display file contents regardless of whether they contain authentication tokens or similar patterns like `auth?token=`.

### Actual behaviour

When asking Q chat to read and print a file that contains strings like `auth?token=`, it doesn't print anything and hangs instead of displaying the file content.
