GridSearchCV always overfits? I built a fix

So I kept running into this: GridSearchCV picks the model with the best validation score… but that model is often overfitting (train super high, test a bit inflated).

I wrote a tiny selector that balances:

how good the test score is how close train and test are (gap)

Basically, it tries to pick the “stable” model, not just the flashy one.
