Then what is it? A transmutation effect? Why doesn't it make the SD incorporeal, two-dimensional, etc.?

It really doesn't say. I don't think it fits neatly into one school of magic.
If you go with the optional rule that there is a -20 penalty for hiding after attacking (from Song and Silence referenced above), and take that a little further by saying you can hide after being seen (ie while "in plain sight") by taking a -20 penalty to the Hide check, you can say that HIPS just eliminates that penalty with magic. It boosts your Hide skill in a specific circumstance by +20. To put that into a school of magic, I'd have to say that it would be transmutation or illusion. But it doesn't alter your body (that would also be transmutation) or appearance (that would be illusion). It certainly doesn't make you incorporeal, two-dimenstional, or even invisible (Invisible creatures cannot be seen with Spot, even though you can become aware of the presence of something, but are vulnerable to see invisibility and the like). The ability description would say as much (or should).
All we know for sure is that it just boosts your Hide skill (though not directly) because of your affinity to shadow. It lets you use Hide in a way that you couldn't before. Items that boost skills can be illusion (cloak of elvenkind, requires the invisibility spell to create) or transmutation (ring of jumping requires the jump spell). Or they can fit into no particular school (ring of swimming requires the creator to have 5 ranks of swim skill). I'd call it primarily illusion if I had to choose, given the proximity of illusion and shadow magic, and that the cloak of elvenkind is the closest magic item or effect to it. But it's not "an illusion" any more than a cloak of elvenkind is...
All IMO of course.
