Slide counter in editor status bar for revealjs presentations

[m20l22]

When authoring revealjs presentations in a .qmd file, there is no way to see
the total slide count without rendering the document. Tools like PowerPoint
display a live slide count in the UI, which helps authors track presentation
length during editing.

Request: Add a slide count indicator to the VS Code / Positron editor status
bar (or the Quarto VS Code extension) when the active file is a revealjs .qmd
document. It could show something like Slides: 12 based on counting level-1
(#) and level-2 (##) headings, updating as the file is edited.

Why it's useful:

• Quickly assess presentation length without rendering
• Helps keep presentations within time/slide constraints
• Analogous to word count for document formats

Workaround today: Manually counting headings via terminal:

grep -cE "^#{1,2} " presentation.qmd

Would you be up for opening this as a feature request on the Quarto VS Code extension?
https://github.com/quarto-dev/quarto

That is what controls the experience of authoring Quarto files in Positron.

Sure. I have done it: quarto-dev/quarto#975
