⚠️ emoji unicode length seems to be messing with visual output

• I am on the latest Hyper.app version

• I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name:
  -- OS Name: Microsoft Windows 11 Pro
  -- Version: 10.0.22621 Build 22621

• Hyper.app version: 3.4.1

• Gist Link Here

• The issue is reproducible in vanilla Hyper.app: yes, the only add-on i have is the hyper-material-theme and disabling it makes no difference

Issue

i checked through all open & closed issues with the word emoji and didn't see anything about this, but i apologize if this ends up being a duplicate.
the issue is that emojis don't seem to be handled correctly in terms of length. for example, if you open up python3 and run

>>> '⚠️' * 10
>>> '⚠️' * 79

and then press up-arrow twice you'll see the preview text as '⚠️' * 710 and if you press down-arrow you'll see '⚠️' * 779 even though if you hit enter on either, the text is actually still the original '⚠️' * 10 and '⚠️' * 79.

you can of course reproduce a similar issue in the normal command-line as well by following:

1. type ⚠️ into the console
2. press up-arrow twice to go to the command before ⚠️
3. press down-arrow then up-arrow. every time you press down-arrow the first letter of the previous command will be appended visually to the current command, although the text still remains as ⚠️
   the image below confirms these reproduction steps in action
   

i believe it has something to due with the fact that len('⚠️') == 2

Start by reproducing the command-history navigation steps in Hyper on Windows 11 and compare the visual command with the text that executes. Trace the terminal input and rendering path responsible for history previews and Unicode width, then verify that repeated ⚠️ characters display consistently and preserve the original command when submitted.
