Merge main branch into dlclive3

Resolved merge conflicts by keeping PyTorch integration changes from dlclive3 branch:
- Kept PyTorch-specific workflow configuration in testing.yml
- Kept PyTorch model references in README
- Kept PyTorch implementation in benchmark.py
- Kept PyTorch support in check_install.py and test_benchmark_script.py
- Removed poetry.lock as it was deleted in our branch
