[Feature]: Improve Test Coverage for Binary Parsers (SafeTensors & PyTorch)

[pipe1os]

Problem Description

Test coverage for the local binary parsers is quite low: pytorch.py is at 21% and safetensors.py is at 45%.

Proposed Solution

1. Review the existing tests/test_parsers.py.
2. Construct simple, dummy binary files (using struct.pack) inside the tests to simulate valid and invalid .safetensors and .pt headers.
3. Assert that the parsers correctly raise ValueError or successfully extract the metadata without needing to commit heavy .safetensors files to the git repository.
