Flatten tensor byte views before deterministic hashing

When hashing a tensor state dictionary, converting a multidimensional `uint8` view directly to a Python list produces nested lists, which cannot be passed to `bytes()`. Normalize every tensor to CPU-contiguous storage, bind name, dtype, and shape, then flatten the byte view before serialization. Add a test with a matrix rather than only vectors or scalars; otherwise the hash helper can survive unit tests and fail only when real model weights arrive. Applies when: producing deterministic receipts for PyTorch model or head initialization. Keywords: PyTorch tensor state dict deterministic hash uint8 flatten bytes receipt
