revert: remove step-based parameterized GQL catalog entries

Reverts the IHasItemDependencies pattern from commit 5639dda.
That approach injected step-level computation (runtime dependency resolution)
into the catalog layer, violating the catalog-owns-declaration / steps-own-computation
boundary and introducing hidden runtime dependencies invisible to the type system.

To be replaced with GqlQuery<TResult,T> — a deferred query handle analogous to
TypedFrame<T> in the Spark extension, where the step decides when to materialize.
