Release v4.165.0

Changed

• Stage loads a model whose execution plan has problems confined to one slice instead of refusing the whole model with STAGE-PLAN-004. Specification runs, the Host and the renderer run the supported artifacts and refuse only the affected commands, queries and read models with a typed STAGE-PLAN-004 refusal; problems that affect the whole model, such as concept validation, still refuse loading. (#501)
• A keyed query with cardinality One is refused per query with a typed refusal instead of blocking every other slice; a specification can no longer pass on such a query only because it has no events and expects no results. (#501)
• The Host's read-model browser API and snapshot queries report a refused read model as refused instead of returning it as empty. (#501)
