Add ph-training: topological approach to hyperparameter optimization

[dancinlife]

Adds ph-training — uses Persistent Homology (H0 persistence) for automatic hyperparameter optimization:

• LR search: H0 CV minimum over 5 epochs = optimal LR (no grid search needed)
• Early stopping: H0 gap between train/test detects overfitting with r=0.998 correlation
• Difficulty prediction: H0 after 1 epoch predicts final accuracy

Verified: MNIST 98.3%, FashionMNIST 87.4%, CIFAR-10 52.0% (with topological early stop).
