Description

Summary:

The pairs plot is a convenient feature, but it can be hard to track divergences when there are too many max treedepth hits. I modified the pairs.stanfit code with a marktreedepth argument and could push if wanted, though it's simple. Perhaps a mark = c('treedepth','divergence') argument or similar would be better.

Research direction

Start by reading the pairs.stanfit code mentioned in the issue and inspect how max treedepth hits and divergences are marked in the pairs plot. Clarify whether the change should add a marktreedepth option or a more general mark argument; done means users can avoid treedepth markers while retaining divergence markers.
