The RubyGems registry wire JSON, decoded into a typed model.

A placeholder boundary mirroring Ecluse.Registry.Pypi.Wire. Écluse serves only npm, so this models just the one shape another part of the system reads from RubyGems: the published version strings of the /api/v1/versions/{gem}.json response, which is a JSON array with one entry per version. Only each entry's number (the version string) is modelled; the rest of the entry (platform, SHA, timestamps) is ignored, leaving room for a full RubyGems adapter to grow the model later.

Unlike the npm and PyPI listings, the document is a top-level array, so parseJSON decodes it as a list of VersionEntry. An entry without a number is a decode failure rather than a silently-dropped element, since a version entry that names no version is meaningless.
