Chat* integration

[sundancecloud]

So we use MarkupEditor in our app, but I am going to poke around with Chat integration. I have a vague idea of an initial use case.

• Uses selects some text.
• User selects from a menu of prompts [see below].
• The text, prompts, perhaps the whole document, or a whole bunch relected docs, are sent off to a Chat* (e.g. ChatGPT).
• The returned text is pasted back into the markdown document
• OR: The returned text is displayed into a preview window and the user can cut/copy/paste/edit back into editor.

Not sure how difficult this will be to add to MarkupEditor. I'll start by trying to POC something, enough to checkout usefulness and usability.

Some possible prompts:

1. Make the selected text clearer, based upon the context documents.
2. Take the selected text as a question/guidance, and suggest text (based upon all the other docs in the context).
   etc.
