bug: Amazon Q Corrupts Terminal Keybindings During Command Completion

### Description
I have tried every version of Amazon Q CLI since July 2024, and all of them have the same terminal behavior issue on macOS. When Amazon Q suggests completions for the flutter command, action keys like Enter, Backspace, and arrow keys stop working correctly.

### 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 15.2.0 (24C101)

### Expected behaviour

The terminal should continue to accept input normally, without altering the behavior of all action keys such as arrow keys, Enter, and Backspace.

### Actual behaviour

After Amazon Q suggests completions for the flutter command, the terminal starts behaving incorrectly:
- Pressing Enter results in ^M being displayed.
- Pressing Backspace results in ^? being displayed.
- Other special characters may also appear in place of their intended actions.

### Steps to reproduce

1. Open a terminal on macOS with Amazon Q installed and enabled.
2. Type the command flutter run -d {device id} where {device id} is a valid Flutter device ID (such as chrome, macos, etc.).
3. As Amazon Q begins to provide command suggestions, the terminal input starts displaying unusual characters when pressing Enter or any other action key.
