+          6.2.1: Patch release picking up upstream JasperFx 2.2.1 fixes:
+                     JasperFx (+ .Events / .Events.SourceGenerator
+                                / .SourceGenerator)        2.2.0 -> 2.2.1
+                     JasperFx.RuntimeCompiler              unchanged (own 5.x line, stays 5.0.0)
+                     Marten / Polecat                      unchanged (9.2.0 / 4.2.1)
+                   No Wolverine code changes — pure dependency bump.
