Preserve Go tuple and pointer type identities

[CaelmBleidd]

Go API type identities collapsed different tuple element schemas and erased the pointer marker in compound types. Render actual typed tuple/pointer names and use class-safe symmetric equality/hash, with cycle-aware inspection of recursive named schemas. This prevents consumers from confusing (bool, int, rune) with a different three-BasicType tuple or struct{int} with struct{*int}.

Targets the actual Go API branch buraindo/go at816194b963, because jacodb-go is absent from neo. This is a small producer fix; no upstream merge is included.

Validation: four GoTypeIdentityTest contracts and the repository checkLicense task passed in a normal clone. Remaining API limits include absent struct field-name metadata, TypeParam binder identity and byte/rune alias normalization; this change does not claim exhaustive Go type support. Consumer native regression validation is tracked separately in USVM #469.

Final head 043845a additionally pins ArkAnalyzer @types/node to 18.19.130 before its existing install/postinstall. Full workflow run 38340695753 passed. Published API artifact a839f86 was verified against its exact commit and all nine modules; the final workflow-only commit does not change API bytes.
