[P] no-magic: 47 AI/ML algorithms implemented from scratch in single-file, zero-dependency Python

I've been building no-magic — a collection of 47 single-file Python implementations of the algorithms behind modern AI. No PyTorch, no TensorFlow, no dependencies at all. Just stdlib Python you can read top to bottom. Every script trains and infers with python script.py. No GPU, no setup, no args. R
