fix(scaffolding): contract scope resolver recognizes H-meta entity kinds

Contract BUILDER-2026-10-04T07:14:03Z-cli, closed: module:construction_decision
correctly_predicted, zero genuinely_unexpected_new.

T4.7 row-1 closure flagged rust-crate:query_memory resolving as
kind=unresolved — classify_surface's prefix set predated the H-meta
entity classes (rust-crate:/go-surface:/config:/workflow:), so
spine-modeled surfaces could never close correctly_predicted.

Red-first: test_hmeta_kind_prefixes_classify_as_structural_entity
failed pre-fix; identity-resolution path needed no change (works for
any id present in an authority). Regression frozen in
test_construction_decision.py (2 new tests, 21/21 file green,
decision neighborhood 107/107).
