"""CatOpt bridge (MVP): CosmosMesh primitives <-> CatOpt-like representation.
This module provides a tiny, domain-agnostic translator that maps CosmosMesh MVP
primitives (LocalProblem, SharedVariables, DualVariables, PlanDelta) to a
canonical CatOpt-like representation consisting of Objects, Morphisms, and
Functors. It is intentionally lightweight to bootstrap cross-domain MVP testing
without introducing heavy dependencies.
