bug: Extend REPL inputs with a large number of lines into the REPL duplicates it

### 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

Amazon Linux 2

### Expected behaviour

#### STR:
- paste input with large number of lines.
- ctl + J a few times
#### Observed:
- screen flickers, but what's really happening is that the terminal is busy duplicating input
- if you scroll up, you will see that your ctrl+v input is duplicated
#### Desired:
- input should not be duplicated when trying to extend input

Suggestions: I would recommend copying Claude Code's behaviour is to add a placeholder, "[Pasted 200 lines; Ctrl + R to review]" rather than actually showing the output; store the input in a buffer. This might not solve the actualy bug, but perhaps make the input more manageable for both users and developers/testers alike.
