Fix PyTorch TransformerDecoder: Seq2Seq Training Guide

Fix PyTorch TransformerDecoder: Seq2Seq Training Guide

While building a custom sequence-to-sequence AI engine for a logistics platform, we discovered a common trap in PyTorch’s standard Transformer examples. Transitioning to a true TransformerDecoder caused training to stall completely. Here is how we fixed target sequencing, causal masking, and positional embeddings to restore rapid model convergence.
