Your fermentation is done, you had a SUPER fast ferment due to the over dose of nutrient in the beginning. It happens sometimes, yeast are living things that we can't perfectly control.
As for what to do, it will be perfectly fine to wait a couple weeks and leave it alone. I usually wait at least a week after primary ferment is over before I rack it, just to give the gross lees (the bigger, chunkier stuff that settles the fastest) more time to settle.
So my advice at this point is put the airlock on it, and ignore it while you do more research. In a week or two you can rack it to a new container. And yes, unless you have some weird proteins (does happen, but is rare) it should clear just fine with time.
