Could the planet have been captured after the ballooned red dwarf shrank? E.g. a wandering planet. Or could something have made its orbit shift, e.g. if it was farther out and now it’s closer in?

It's possible that it's captured, but the article said that it had a nearly circular orbit, so I think that that makes it less likely.
