Description
@avehtari pointed out that projpred does not complain when using a (brms) reference model with a truncated response distribution (truncated normal in his case). At the very least, I think projpred should throw a warning for such reference models, stating that the truncation is not taken into account when performing the projection. As a longer term objective, we could check whether it is possible to take the truncation into account.

Research direction
No files or tests are named. Start by tracing how projpred handles brms reference models and response distributions, then find the validation or warning path for truncated models. Done for the immediate scope when such models warn that truncation is not included in the projection; accounting for truncation itself is identified as a longer-term objective.
