Core types for Cloacina computation graph plugins.
This crate contains the types that packaged computation graph cdylibs need
at compile time. It is the computation-graph equivalent of cloacina-workflow
— a thin crate that avoids pulling in the full engine.
The #[computation_graph] macro expands into code that references types from
this crate. Embedded-mode users get these types re-exported from cloacina.
