Summary

• Use the official 11.0.0-preview.1.26555.1 extraction dependencies, whose .NET Standard assets depend on stable System.Text.Json 10.0.13.
• Remove the explicit System.Text.Json RC3 references from the portable tests and package smoke consumer.

Validation

• 649 tests with .NET 10 provider assets and 649 with .NET Standard 2.0 provider assets.
• Packed-provider smoke checks for both assets using an isolated NuGet cache.
• Confirmed extraction restore graphs no longer resolve System.Text.Json RC3.
