Summary

• The source generator now binds a connection's Edges field to the generated edge type (for example AuthorEdgeType) when the connection class is declared in a referenced assembly. Previously it emitted the bare runtime symbol name (PageEdge, or a custom PageEdge<T> subclass), which produced generated code that did not compile (CS0234 / CS0311).
• TestHelper gains CreateReference and a GetGeneratedSourceSnapshot overload that accepts additional metadata references, so analyzer tests can place types in a separate assembly.

Test plan

• New PagingTests snapshot tests for a PageConnection<T> subclass and for a ConnectionBase connection with a PageEdge<T> subclass, both declared in a referenced assembly
• Both snapshots captured emit diagnostics before the fix and are clean after it; verified on net8.0, net9.0, net10.0, and net11.0
• Full HotChocolate.Types.Analyzers.Tests project passes (339 tests, net10.0)

Closes #10141

Pull request overview

This pull request fixes a HotChocolate Types source generator edge-case where connection Edges fields were bound to an invalid edge CLR type when the connection/edge runtime types come from a referenced assembly, causing generated code to fail compilation. It also extends the analyzer test infrastructure to compile and reference an additional in-memory assembly, allowing coverage of cross-assembly symbol-binding scenarios.

Changes:

• Fix connection type transformation to use the generated edge GraphQL type wrapper name (e.g., AuthorEdgeType) instead of the runtime edge symbol name when building ConnectionTypeInfo.
• Add TestHelper.CreateReference and a GetGeneratedSourceSnapshot overload that accepts additional MetadataReferences.
• Add new paging snapshot tests covering PageConnection<T> and ConnectionBase<...> cases where the connection/edge types live in a referenced assembly.
