Add a per-node Help section to the workflow editor's node detail pane:
description, configuration, inputs, outputs, and edges for every node
kind. Keys off the effective kind (preserved IR kind) so graph-only
policy nodes — auto-merge gate, branch-group member integration /
promotion, PR and recovery nodes — get specific help instead of reading
as a generic merge/gate/hold, and are flagged "Engine-managed".
