Does a higher developer dilution (compensated by an extended developing
time) increase or decrease grain or granularity?

My understanding, which is very limited, is that it depends. With high alkalinity developers that have little buffering, such as Rodinal, diluting causes a lowering a alkalinity and hence finer grain. With high sulfite style developers (d76, xtol, d23...) diluting causes larger grain, because there's a less concentrated sulfite solution.
