Direct editing of notebook files in your text editor of choice, with side-by-side rendering of notebook outputs

Description

Direct editing of notebook files in your text editor of choice, with side-by-side rendering of notebook outputs. This ticket is for the first iteration which does not need to include deep integration with vim/pycharm/etc, just yet.

Instead we can allow editing the file and pushed changes to the marimo editor on save.

Suggested solution

marimo edit --watch. This will watch any files being edited (polling or watchdog if installed). When the file changes, we resolve the diffs and send updates to the marimo editor.

I've been editing marimo notebooks in my editor, while running the notebook at the same time.
To see the changes, I have to restart the kernel.

Alternative suggested solution

It would be good to have a "reload notebook" button that loaded the changes. Perhaps "reload cell" to limit the impact?

I realise that there could be downsides such as state inconsistencies, increased complexity and confusing behaviour.

Additional benefits

As well as being able to use your preferred editor, you could also leverage existing AI editing tools e.g. https://github.com/Aider-AI/aider to edit your notebooks
Instead of marimo needing to reinvent the wheel of AI-assisted coding, we could use already existing tools.
