Subject: [PATCH] StyleCop: net10.0, OpenAPI without Swashbuckle, .editorconfig
 sample

Retarget both projects from net7.0 to net10.0. Drop Swashbuckle.AspNetCore
and wire Microsoft.AspNetCore.OpenApi 10.0.12 with AddOpenApi() and
MapOpenApi(), as the .NET 10 template does. Add the .editorconfig the
article edits, demoting SA1101 to a suggestion. Register stylecop.json as
a bare AdditionalFiles item (the analyzers read it at compile time, so
CopyToOutputDirectory did nothing). Bump the test packages.
StyleCop.Analyzers stays on the stable 1.1.118.
