Artifact boot requests can pass a share key and vanity params, and a syncLive option enables a live-synced read.

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.
