The artifact tool's new "quickstart" action no longer requires write confirmation

What

The artifact tool keeps a list of actions considered read-only or non-destructive, so they can run without asking for write confirmation. The quickstart action has been added to that list, alongside actions like read, list_types, and describe_type.

Why

Since quickstart doesn't modify anything, this lets it run without prompting for permission, the same way other informational artifact actions already do.
