“Dual Action Truss Rod?”
Can someone tell me what is meant by the term “dual action” when referring to the truss rod?

It means it can bow the neck forward, or back -

So are most truss rods dual action or is this a feature found on just higher end guitars?

FWIW I've purchased a couple of the double action truss rods for my hobby builds. I'm on the fence on whether they're at all helpful with "back bow" by pushing away from the fretboard. They seem to be more functional when adjusted clockwise and push up on the fretboard. Take my opinion with a grain of salt though; I tend to break things.

Some ( most? ) luthiers consider dual action truss rods a solution to a problem that doesn’t ( or shouldn’t ) exist, if you know how to build. I think they come from the electric guitar world, or maybe someone just figured out that you trap a threaded rod at both ends and it can pull or push, so call it a feature and add to the price.
It’s more of an engineers solution, than a luthiers -

The above web article would differ from it not being a luthier's solution.

https://youtu.be/PgKB7DRf4QU Most shops and almost all larger companies are using double action rods - its a minimal increase in cost, sounds great in marketing, and it allows the customer to make adjustments as they want, whether they are using super slinkies on their baritone, or baritone strings on their parlor. And I dont see alot of adjustable bridges on flat top guitars - I would bet a number of techs could tell you about improperly adjusted double action rods. And there are some very high end instruments made without any truss rod at all - its like the spanish heel vs dovetail neck join vs the bolt on - is it really a luthiers solution, or an engineers, or just an alternate technique? You can believe however you want -
