Update generated artifacts for shard-wiki entries (catalog, export, graph, federated index)

Recompose federated index (20 capabilities) so relation resolution includes the
8 wiki.* entries; regenerate registry.json/search.html, CapabilityCatalog.md, and
the relation graph. graph --check: clean. validate: ok.
