test(code-graph): add fixture for Go generic functions and types (Go 1.18+)

What does this MR do and why?

Adds a YAML integration test fixture covering Go 1.18+ generics. The fixture exercises generic function extraction (Map), generic struct extraction (Set), a constructor for a generic type (NewSet), and a method on a generic type (Add). Without this fixture, a regression in generic function/type extraction would not be caught by CI.
