AshDispatch.Extensions.AddUserRelationship (AshDispatch v0.5.1)

Spark DSL extension that adds a user belongs_to relationship to DeliveryReceipt.

This allows consuming applications to add a proper relationship (instead of calculation) so that AshTypescript can load nested user fields.

Usage

Configure in the consuming app:

config :ash_dispatch,
  user_resource: MyApp.Accounts.User

When the consuming app compiles, the transformer will:

1. Check if user_resource module exists
2. If yes: Remove :user calculation and add :user relationship
3. If no: Leave :user calculation as-is

This avoids compile-time warnings when ash_dispatch compiles standalone, while providing a proper relationship when compiled with the consuming app.
