Does deep litter require a roof to be pleasant? Not a moldy messWelcome!
Your easiest plan would be to use deep litter in the runs, because the total run space that you have per chicken really won't allow rotational grazing without overcrowding the two pens while the third regrows. Bagged shavings, wood chips (not all black walnut or cedar), grass clippings, hay, straw, weeds, whatever, will be loved by them, as they dive for bugs and worms, and turn it all into compost.
Plantings around the outside can be shrubs for more summer shade, and as mentioned, most of the herbs aren't eaten, and that includes catnip. I think that trying to protect edible plants inside these runs will take more effort than it's worth, and all that manure on dirt, plus rain, won't be so nice over time.
Your run area does drain well, I hope! Mud will be awful!

My chickens are obsessed with chives. I'm growing it in pots to rotate drive m since they'll eat them to the dirt. Bonus: they propagate via division and seeds, so it spreads very easily.
