Bind the 38-entry field-descriptor table (frozen ensure_schema_2d
order) to cfg. No casefold flags: the 2D reader already stores
lowercased selectors, and the engine's choice compare casefolds the
candidate anyway, preserving the direct-call validate_config_2d
mixed-case tolerance. Help texts are empty (the 2D schema never
published help).
