git cd should offer to stash/stash pop your changes when creating a new branch

[pchr-srf]

Currently, trying to start a new branch while having unstaged changes works like this:

$ git-cd start my-fancy-new-branch
git-cd start
Executing: git checkout main
D       some/file/i/deleted.js
M       some/modified/file.php
A       some/new/file.md
Your branch is up to date with 'origin/main'.
Executing: git pull origin main
Error: 
error: cannot pull with rebase: You have unstaged changes.
error: additionally, your index contains uncommitted changes.
error: please commit or stash them.

Ideally, it would work like this:

$ git-cd start my-fancy-new-branch
git-cd start
Checking if there are unstaged files...
Whoops, you got some unstaged files! Should I stash them and then re-apply them after [y/N]?
$ yes please, thank you
Executing: git stash
Executing: git checkout main
Executing: git pull origin main
Executing: git checkout -b my-fancy-new-branch
Executing: git push origin my-fancy-new-branch
Executing: git branch --set-upstream-to origin/my-fancy-new-branch
Executing: git stash pop

My current workaround is to enter git stash && git-cd start my-fancy-new-branch && git stash pop
