A docs/type-related artifact tool is now gated behind new typeCatalogOn, typeCreateOn, quickstartOn and docsTypeOn flags

What

A tool related to artifact types and quickstart documentation is no longer always offered. It's now included in the tool list only when a set of flags are enabled together: typeCatalogOn, typeCreateOn, and quickstartOn (or, in the Cowork-host variant, docsTypeOn).

Why

This lets Anthropic control the rollout of this tool independently per account, rather than shipping it to everyone at once.
