The path takes `publisher` from the manifest verbatim, so a plugin published
by officerdev lands under officerdev/. `officer/core` is not a plugin at all —
it is the platform's own, shipped by the setup script from the capabilities
repository.
Two spellings marking two different things: platform versus publisher. Arrived
at by accident and kept on purpose. Recorded because the obvious tidy-up
removes the distinction rather than the inconsistency.
