Support notebook cell output inclusion in context

When working with Jupyter notebooks, the output of the cells is a very important piece of context for any Cursor feature. As an example, having it in the model context for cmd+Tab would be very helpful for smart autocompletions. Also, being able to discuss about that in the chat format would be great.

I understand that there are little guarantees on the useful information density of cell outputs, but at least it would be great to include reasonably sized outputs just as any piece of code
