Method extract_anonymous_class

codegraph-kernel/src/csharp.rs:1098–1131

extractAnonymousClass — `new T() { ... }`. The C# grammar never produces a class_body/declaration_list child on object_creation (object initializers are initializer_expression), so this is unreachable — mirrored from the shared TS path like java.rs.
