Hi,
Sorry, but that just isn't a worry, unless you drove the entire way with the parking brake on or riding the brakes. A rotor is designed (in both it's casting and the material used) to shed heat. That's it's purpose, to transfer the mechanical and inertial energy of the car to heat energy and expell it from the system to atmosphere.
By the time you pulled in, shut the car off, insert your quarters and finally sprayed some water on the rotors, they would have cooled sufficiently that no warping could take place. Besides, these aren't can lids, they are composed of high carbon content steel and you'd have to go from 850° to -40° near instantaneously to cause any warping. You're obsessing, it's all good...
Happy Motoring!... Jim'99
