Lookup key for a named type: every segment of its spec id.
Two types with the same declared name in different crates or modules are
distinct, so named-codec maps from buildNamedCodecs are keyed by
this rather than by declared alone. The encoding is injective; use
formatSpecId for anything a person reads.
