Pull request overview

Adds EF Core design-time integration to automatically generate GraphQL DataLoader sidecar files during migrations scaffolding, and updates the generator output to better match GraphQL conventions (ignored FK scalar fields, improved notes/docs).

Changes:

• Introduce a new Stackworx.EfCoreGraphQL.DesignTime project with an IMigrationsCodeGenerator that generates {Snapshot}.DataLoaders.g.cs + a hash sidecar.
• Update core generator to support design-time (string generation from IModel, pass DbContext type instead of instance) and emit ExtendObjectType(... IgnoreFields = ...) for redundant FK scalar fields.
• Enhance many-to-many generation with explicit XML doc notes and update tests/sample outputs accordingly.

The comment says design-time generation can “safely pass null”, but the code now passes contextType into Generate(...). Update/remove the comment so it matches the current implementation and doesn’t suggest null is expected/allowed.
