EnergiBridge Skeleton: canonical bridge between GridVerse primitives and a
vendor-agnostic intermediate representation (IR) inspired by CatOpt-like
intermediates.

This module provides a small, production-friendly helper set that a future
implementation can plug into the GraphContractRegistry and Adapter Marketplace
to enable cross-domain interoperability without rewriting solvers.
