Release v0.26.0

Added

• Generated models link commands to the events their handlers append through Marten Events.Append and StartStream, and through Wolverine aggregate handlers (#80)
• Public diagnostic codes WolverineDiagnosticCodes.ProductionLinkOmitted and CritterStackDiagnosticCodes.MixedSliceKindsSplit identify omitted production links and split feature slices

Fixed

• A command, its aggregate, events, read model and endpoints sharing one flat feature namespace are split into slices by artifact instead of failing generation with GEN0007 (#81)
