Create app.py

this version if apply fine-tune mushroom classification
Loads your fine-tuned PyTorch ResNet model.

Uses only two main classes: "Edible" and "Poisonous".

When the model predicts a class, it shows extra information suggesting possible mushroom species from your dataset:

Edible → "Amanita citrina", "Russula delica", "Phaeogyroporus portentosus"

Poisonous → "Amanita phalloides", "Inocybe rimosa"
