Replace pybind11 + torch/extension.h bindings with PyTorch's stable ABI (STABLE_TORCH_LIBRARY, torch::stable::Tensor, torch::stable::Device). This decouples the extension from specific PyTorch C++ ABI versions. - Register ops via STABLE_TORCH_LIBRARY + TORCH_BOX instead of PYBIND11_MODULE - Replace torch::Tensor/Device/Dtype with stable::Tensor/Device and headeronly::ScalarType throughout - Replace torch::from_blob with torch::stable::from_blob - Add kvcached/vmm_ops.py wrapper that loads _vmm_ops_lib and re-exports ops via torch.ops.kvcached.*, preserving existing import API - Remove torch_python from linked libraries, rename extension to _vmm_ops_lib - Remove dead free_ftensor_() and torch_utils.ipp Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> Signed-off-by: Christian Heimes <cheimes@redhat.com>
