Release v4.136.0

Changed

• Rendering now admits concepts that use generate rule (ESM v21). Stage compile-checks the attached C# body against the BCL and Fundamentals and emits it as the concept's IGeneratableInContext<T>.New(GenerationContext) factory, so the rendered application generates the value with the tenant and time of the operation. A body that does not compile or that produces a compiler warning is refused with STAGE-ESM-019 at its source location; type or namespace shadowing is refused with STAGE-ESM-022, and a missing attachment with STAGE-ESM-020. The Host and the legacy syntax engine still refuse commands that generate a generate rule value with STAGE-ESM-028. (#414)
