Re: [FEATURE] Proposal: git stash --only-unstaged

> **Proposed feature:**
> A new option, for example: git stash push --only-unstaged
>
> ---
>
> This would:
> - Save only the unstaged working tree changes to the stash.
> - Leave the index both in the working directory and completely absent
>   from the stash object.
> - Make `stash pop` safe even if the index has changed in the meantime.

>
> **Benefits:**
> - Cleaner workflows for splitting commits during interactive rebases.
> - Safer testing of staged changes in isolation.
> - Avoids unnecessary conflicts on stash pop.
