…start__/__end__ type labels - Fix truncate_graph cycle handling: use modified Kahn's algorithm that force-processes the highest-layer unprocessed node when topo sort stalls on cycles, and skip layer updates for already-processed nodes to prevent back-edge inflation - Fix _type_label to check node.name (not just node.type) against hidden labels, so __start__/__end__ nodes with type="node" are correctly hidden - Bump to v0.1.8 and regenerate screenshots Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
