/**
 * WGL048: Pipeline Without a Name
 *
 * Flags a pipeline that defines a `workflow:` block but no `workflow:name:`.
 * A pipeline name shows up in the GitLab UI and audit output; naming pipelines
 * makes runs easier to identify and review. Only flags pipelines that already
 * customize `workflow:` (where a name is cheap to add and most useful).
