If it were my car, I'd double check every single torque value on the braking system and front suspension against the service manual. Tap on things with a rubber mallet and see if they move. Pull out the pads and see if the pistons move freely and completely retract into the calipers. You may find nothing is out of whack. You might find something the dealer missed. If everything checks out, scuff up the rotors and pads slightly, go get the directions for bedding pads off Stoptech's website and go do it again yourself. If all of that solves your problem, fantastic. If not, you've just eliminated another variable.
Something is wrong with your specific car. Few people have had rotor issues, and those that had them solved it when they went to aftermarket pads and rotors. You've changed out pretty much everything but the calipers, master cylinder and ABS unit, and the problem still occurs. This suggests to me that the root cause is not a braking issue, and the warping of the rotors are a symptom of something else being wrong. That makes me think something gets out of line when the nose dives under braking. You've claimed that the rotors were previously toasted in a single stop. That's not normal at all.
