Please just use *GNU* readline

### 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 15.7.2 (24G325)

### Expected behaviour

1. I can turn off bracketed paste
2. A _single_ Ctrl+D exits the application
3. I can modify other readline behavior to suit my needs
4. I am able to use the cursor-right key to edit my query

### Actual behaviour

The readline library you are using is awful.

1. I cannot disable bracketed-paste,
2. I typically mean quit when I type Ctrl+D,
3. has no means to modify its behavior to suit my needs, and
4. now, most recently, broke the cursor-right in Terminal mode.

Please just use GNU readline instead of what you are using.
