1.45.5

(fix): Fix compile errors in generated Go SDKs where the v2/ TypeScript client, its generated tests, and the generated dynamic snippet tests referenced types in their original package after the v1 generator had relocated those leaf types into the shared common package to break an import cycle. The v1 generator now records the relocations in a sidecar that the v2 generator reads, and also writes them to a host-readable file (when the Fern CLI asks for it) so the CLI’s dynamic snippet test generator references the relocated types from the same package too.
