Claude can no longer auto-edit an artifact comment thread when the read version isn't the live, owner-visible one

What

The function that decides whether an artifact comment thread can be auto-edited now checks the artifact's audience and audience view before allowing the edit. If the version that was read is a pinned snapshot rather than the live, owner-visible version, the edit is now refused, and a new telemetry event is recorded for this case.

Why

This prevents Claude from editing an artifact based on an outdated or restricted snapshot rather than the actual current version the owner sees.
