Add a State Hub workplan/wait graph as a Fabric explorer mode.

Coordination is a view, not topology. Open workplans and wait tasks
project into graph-explorer; citation edges recover depends_on from
task prose. UI: /ui/graph-explorer?mode=coordination.

+
+State Hub remains the workplan authoring surface. Fabric already has a
+graph-explorer shell. This plan is a *perspective*: open workplans, open
+tasks, and wait/depends_on edges, so the 100+ loose ends are inspectable.
+
+First slice (this file's companion commit):
+`export --format coordination` and
+`/ui/graph-explorer?mode=coordination`.
+
+## Host the coordination overlay next to Fabric topology

+```task

+
+Keep the projection a read of State Hub. Add mode switching without a full
+page reload, chokepoint sizing from in-degree, and a hosted registry path
+under RAIL-FAB-WP-0028 when that authority exists. Do not let Fabric become
+the place workplans are edited.
