Catch costly PyTorch bugs before they waste your GPU hours

Torch-preflight is the kind of tool PyTorch developers didn't know they needed until they saw it. The author spent years watching simple mistakes, like forgetting `zero_grad()` or holding onto autograd graphs, burn GPU hours. Instead of waiting for failures, this linter reads your code without importing or executing it, catching those bugs upfront. With 13 rules and VRAM estimation that lands within 4% of measured peaks, it's practical and honest.
