Entity Blueprint Server

vyuh_entity_blueprint_server integrates entity blueprints with vyuh_server.

It provides:

• entityFeature(...) for registering a blueprint module as a server feature
• BlueprintServerRuntime for accessing the composed blueprint, trigger executor, outbox dispatcher, and REST router
• server adapter wiring for database, query, policy, auth, telemetry, and route integration

This package is integration glue. The executable runtime contracts live in vyuh_entity_blueprint_runtime.
