Notes

• Test projects already target net10.0
• Source project maintains netstandard2.1 and netstandard2.0 targets for Service Fabric compatibility
• Autofac.Extras.DynamicProxy remains at 6.0.1 for inter-Autofac dependency coordination
• ServiceFabric packages updated to compatible versions (11.0.0 + 8.0.0 family)

Test plan

• Build succeeds locally with dotnet build (using /p:NuGetAudit=false to bypass local vulnerability database access issue)
• CI will validate full build and test suite on appropriate architecture
