Fix PyTorch bool dtype promotion

[FlorianPfaff]

Summary

• Add a PyTorch backend compatibility shim that replaces convert_to_wider_dtype with a torch.promote_types-based implementation.
• Wire the shim into backend support initialization so raw PyTorch helpers use the corrected promotion behavior.
• Add regression tests for mixed boolean/numeric allclose and isclose inputs.

Bug fixed

The PyTorch backend's promotion table did not include bool/uint8 and other non-default numeric dtypes. Mixed boolean/numeric comparisons such as allclose(bool_tensor, uint8_tensor) and isclose(bool_tensor, float_tensor) could therefore leave incompatible dtypes unchanged and raise a Torch dtype mismatch, while NumPy promotes the operands and succeeds.

Testing

• Added tests/backend_support/test_pytorch_dtype_promotion_contract.py.
• Not run locally in this connector environment; CI should execute the regression tests.
