Devlog 8 - StudyBuddy

im too lazy to have a full write up for this (watched spiderman tdy IT WAS REALLY GOOD)

• for each topic that a user gets wrong, a seperate model (gpt-oss:20b, sorry if i miswrote the model) gives a walkthrough of the topic

• also added missed questions to the csv export

• added a AI answer key system if the worksheet doesnt have one.
