Release v4.79.0

Added

• CompositionOptions.namedTemplateOnly composes a screen with only the template it names, not inside the templates that template fits. A modeled screen fills only its own template's slots, so outer templates could only draw their seeded content, for example a workspace's module navigation showing "Nothing here yet" beside a master/detail. Hosts that render modeled screens can set it; leaving it unset keeps today's composition. (#246)
