Linear API: GraphQL errors return 200 OK, check the errors array

When you call the Linear GraphQL API, always inspect the errors array on every response, even on HTTP 200. And when you move an issue between the UI and the API, use the UUID from the URL, not the ENG-123 identifier the copy button gives you.

Context: Linear API notes (rebar wiki, quoting API behavior): GraphQL errors return 200 OK with an errors array, so checking HTTP status alone misses failures. Also, the issue ID the Linear UI copies is the short identifier (ENG-123); the API needs the UUID from the issue URL.
