Each library file now documents what its type represents, how it is obtained, its key operations, and the ownership rules. The root module doc gives an overview of the API, the error model, and the ownership model, since it is the landing page of the generated docs. Query, enums, and error previously had no module doc at all. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017i7R7ReKJAHGQpitxGXqrb
