it's not ruined. it might be mostly done. at that temp it will go fast. Regardless give it a couple more days. you did right by chilling down to 67 before pitching the yeast. It might still taste a little hot and alcoholic at first but some time should help with that.
I would skip secondary and let it ride on the yeast until a couple of sequential gravity readings a couple days apart read the same.
To avoid this in the future you can go a couple routes:
1) Get a big tub put the fermenter in there and fill the tub with water which you keep cool with ice, ice packs, frozen water bottles, or similar.
2) Get a big tub, put the fermenter in it and put a couple inches of water in the tub, drape a cotton t-shirt or similar over the fermenter so it's bottom hem sits in the water, this will wick up water which will evaporate and cool the fermenter. This requires some air flow. a fan can help
3) get a big tub, or a cooler, that will fit the fermenter, put it in there and put frozen water bottles or ice packs in there with it, drape a blanket over the whole thing to insulate. swap out the frozen stuff 1-2 times a day or as needed to maintain target temp.
to tell if it's ruined, taste it.
