So, is there anything that can reliably keep the cats in their half the
house? I'm thinking about a latch for the doors. The sticking point is
finding something that's easy for humans and impossible for cats, can be
operated from both sides, and doesn't make it look like we're in a
prison.

How about a hook and eye near the top of the door? Not beautiful but it
would work.

Hook and eye is inoperable by cats, especially these cats. It can't be
higher than a seated person can reach, but about as high as a doorknob
should be OK. It'd have to have enough slack in the mechanism to allow
a hand through so you could work it from both sides; I dunno if you can
do that unless your hook is long enough to allow enough of a cat through
to put significant force on the mounting.
