gRPC-only projects couldn't call app.UseSvrntyCqrs() without adding the
MinimalApi package. The method only calls ExecuteMappingCallbacks() which
is already in core — it had no MinimalApi dependency. Adds ASP.NET Core
FrameworkReference to the core package.

Scaffolds a complete Svrnty.CQRS project from a natural language
description — creates solution, web project, DAL with PostgreSQL,
entities, Program.cs, first feature, proto file, and .editorconfig.
Defaults to gRPC-only; MinimalApi added only on request.
