Every module follows the assigner's new places: the contracts' go/ path, mesh-wants in the delivery contracts, the state and tool assignments (issue 1966)

The legacy key form placement.<node> is gone from the client, so the readers and their fixtures lose it. The check noplacement
now also refuses the assigner's retired names in a manifest.
