GridVerse MVP Scaffold

Overview
- Lightweight, extensible core for cross-domain optimization with a canonical registry and adapter marketplace skeleton.
- Core primitives are represented as in-memory contracts (LocalProblem as Objects, SharedVariables as Morphisms, Adapters as Functors).
- Provides a minimal ADMM-like solver and delta-sync stub for offline/partitions handling.

Tech Stack (initial)
- Python 3.x, numpy for numeric helpers, pytest for tests.
- In-repo registry and adapters with TLS transport stubs (not implemented in this minimal scaffold).

How to use
 - Run tests with: bash test.sh
- EnergiaBridge Skeleton: Added gridverse/bridge_energia.py and a README note describing canonical interoperability bridging.
- Next MVP steps (Phase 0): finalize core protocol and 0.2 contract schemas, implement two starter adapters (e.g., DER controller, building load controller), and wire a minimal ADMM-lite solver with delta-sync scaffolding. Ownership: to be assigned.
- Extend with real adapters and a full TLS transport layer in subsequent iterations.
- EnergiBridge MVP: add a canonical Interop Bridge (EnergiBridge) that maps GridVerse primitives to a vendor-agnostic IR and supports delta-sync, TLS transport, and conformance checks. Phase 0 focuses on protocol skeleton and two starter adapters; Phase 1 adds governance ledger and identity; Phase 2 adds cross-domain demo; Phase 3 hardware-in-the-loop validation.

Testing Rules
- Tests run via pytest. Packaging checks run via python -m build.
- Keep changes small and backwards-compatible by default.

Contribution Guide
- Use the gridverse package namespace (gridverse.*).
- Add new adapters under gridverse/adapter_marketplace/ with a consistent interface.
- Update tests to cover new contracts and adapters.
