https://hibernate.atlassian.net/browse/HSEARCH-4574 adds a few annotations to map constructor parameters to various projections, but not @DistanceProjection because that projection depends on a “center” generally set at runtime, so we need to work on https://hibernate.atlassian.net/browse/HSEARCH-4806 first.

Once that’s done, we can introduce @DistanceProjection:

record MyProjection(
@IdProjection id,
@DistanceProjection(fromParam = "center") double distance) {}
