Bug Report

Describe the bug
In <CopilotTextarea>, cmd + k works on a Mac to bring up the popover. However, on Windows, ctrl + k does not.
This could potentially be the case in other places where we use keyboard shortcuts.

To Reproduce
Steps to reproduce the behavior (the easier it is to replicate, the sooner it will get fixed):

1. On a Windows machine, go to https://crm-demo-delta.vercel.app/
2. Focus on the textarea field
3. Type ctrl + k to open up the CopilotKit popover

Expected: The popover opens as it does on a Mac when using cmd + k.
Actual: Nothing happens

Potential Solution

We might want to look into dedicated shortcut handling libraries for JS/React that handle cross-platform key mapping differences. We need to make sure it's fixed in other places that keyboard shortcuts.
