SC-NeuroCore — Stable Engine Bridge Contracts

Stable engine consumers should use explicit wrapper modules under bridge/sc_neurocore_engine/, not the top-level sc_neurocore_engine namespace as a generic export bag.

Current maintained wrapper surfaces:

• sc_neurocore_engine.network
• sc_neurocore_engine.studio
• sc_neurocore_engine.world_model
• sc_neurocore_engine.photonics
• sc_neurocore_engine.dna
• sc_neurocore_engine.quantum

Why:

• explicit import points are easier to test
• capability failure becomes local and diagnosable
• consumers stop depending on unrelated re-export churn in bridge/sc_neurocore_engine/__init__.py
• mypy can be paid down module by module instead of treating the entire top-level bridge as one dynamic surface

Rule:

• runtime code should import the narrow wrapper it actually needs
• top-level re-exports remain compatibility surface, not the preferred implementation contract
