Module ext_op 

Out-of-tree extension-operation mechanism.

This module implements the ExtensionOp trait and its process-local registry. Together they let external crates contribute fused primitives that participate in the crate::std_tensor_op::StdTensorOp graph through the single carrier variant StdTensorOp::Extension(Arc<dyn ExtensionOp>).

See docs/spec/extension-op.md for the normative contract. Key points:

• Identity / hashing / equality are expressed on the trait so the type-erased Arc<dyn ExtensionOp> carrier can satisfy Clone + Hash + Eq + Send + Sync + 'static (computegraph’s GraphOperation requirements).
• AD rules are owned by the semantic AD registry in tenferro-ad; this extension-operation contract does not import an AD engine.
• Extension ops themselves do not require process-global registration. Frontends carry them directly as Arc<dyn ExtensionOp>.
