• Add a read-only DiagramView for plugins (79fd7827)

  Plugins can now draw boxes and arrows in Studio's style: import DiagramView from @artemis-studio/plugin-sdk and pass plain nodes and edges. It is laid out for you (layered, off the main thread), and a node or edge label change never moves anything.

  • selectedId and onSelect tie it to a detail pane.
  • A node with state 'error' or 'warning' shows the word on the card and reads its reason out.
  • The diagram is one tab stop: arrow keys move between nodes, Enter selects, and the selection is announced.
  • It is read-only: nothing drags or connects.

  See ADR-0117 and the plugin guide.
