bug: Pasting no longer works in VIM

### 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 15.7.1 (24G231)

### Expected behaviour

Hi there,

When I open VIM, and paste in a certain amount of content (sorry, I can't really share the content, but it's usually a large, (in this case, 3000+ lines) of code (this could be Python code, this could be a JSON document, etc), then VIM, and my terminal completely freeze. I can't reproduce it in a way that 3000+ lines of JSON will always freeze, it seems to be random (maybe because my JSON contains a lot of URLs or so, I'm not sure). As a test, I've also copied the complete content of https://en.wikipedia.org/wiki/Europe (just browse to the site, copy and paste the whole website) into VIM, and I can reproduce it: VIM completely crashes. If I just paste it in my terminal, no issue. When I remove Q cli, all works again fine. This makes Q very unusable for me.

I'm using iterm2, but when I use MacOS terminal, I have the same issue. I've tried using PICO instead of VIM, and no issue with PICO.

### Actual behaviour

When I do a paste of the content in my buffer, the terminal completely freezes. Without Q CLI, it doesn't.

### Steps to reproduce

See above.
