Subject: [PATCH] feat(go): promote Go to MIGRATED_LANGUAGES

Go scope resolution is now enabled by default (no REGISTRY_PRIMARY_GO=1
env var required). Legacy parity gate will auto-run Go resolver tests on
both paths for every PR. All 116 integration tests pass on both legacy
and registry-primary paths.
