Formatting causes all headings and lists to unfold

Running Prettier: Format all content causes folded headings and lists like these:

to expand fully, like this:

I figure this is likely because the entire file is being replaced, but perhaps there is a way around that.

Yes, that's the key thing.

but perhaps there is a way around that.

There may be a way to detect which sections are collapsed, though I'm not sure how to do that right now.

However, I've implemented a workaround in the code: the file contents are only replaced if the text changes after formatting. This approach prevents the formatter from unfolding collapsed sections.

I am unfamiliar with Obsidian's developer API, so I don't know if there's a built-in for this, but what do you think about this:

1. Before running Prettier, cache the current folds stored in localStorage[${app.appId}-note-fold-${path}] (you can use the undocumented method app.foldManager.loadPath() to get folds)
2. Format content
3. Set the folds cached in step 1 (I assume using app.foldManager.savePath(), but I couldn't get this working)
