@logion/node-api (Apache-2.0) and @digitalnative/type-definitions (MIT)
were imported only for their type definitions, and each brought an old
@polkadot/api tree with it (util-crypto 6/7, elliptic, uuid). The
definitions are now in the spec files, with their source and license.
Checked by serialising each resulting bundle with key order and
undefined preserved: byte-identical to what the packages produced
(logion 27715 bytes, standard and opportunity 1778 each).
RegistryTypes does not model a struct's `_alias` map, which the registry
accepts; the merged latest logion types are cast at that one point.
