I'm not aware of anything built-in.
One way would be to use buffers: you enter your text into two buffers ("left" &
"right"); compare them using a script which then modifies the buffers to
highlight the changes in red or green; and then \getbuffer the buffers from
inside the columnset commands to print them.
There's a good discussion of comparison algorithms at the link below, including
source code in Javascript (but not Lua, unfortunately). However, Context
supports Javascript with \startJScode ... \stopJScode so you could try adapting
what's there.
