Artifact publish/read gains syncLive mode and a neverPublished error state

Artifact publish takes a syncLive option and can report a distinct never-published error instead of a generic one.

The artifact publish and read path now accepts a syncLive option; on a frame read it appends live=sync to the request, alongside new support for sk (share key) and vanity params on the artifact boot request.

A 404 on artifact read no longer folds every failure together: it now distinguishes an artifact that exists but has never had anything published to it from one that is genuinely missing or unshared, returning a neverPublished flag with a clearer message.
