highlightNodes

Highlight one or more nodes in the graph with a coloured ring. Replaces any existing highlights — call again with a new set to update, or use clearHighlights to remove all rings. The highlight ring appears just outside the node circle and is visible alongside any selection ring the user may have active. Topic IDs must match the full path as seen in the visualiser (e.g. 'home/kitchen/temp'). Unknown topics are silently skipped and reported in the response.
