Partials

Use @Partial for fragment responses.

@GET("/users/table")
@Partial(template = "fragments/users", slot = "rows")
public final class UsersRows extends ViewHandler {
    @Override
    public ViewModel render(dev.relism.models.Request req) {
        return ViewModel.of("users", List.of());
    }
}

If slot is empty, the adapter default slot is used.

If a slot is specified but the adapter does not support slot selection, startup fails with a clear error.
