R-5: the tool runner follows the assigner's views of the module that claims the seat, named by the seat

The holder is read from the catalog half's entries serving a verb of mesh-module-assigner, on the branch follower's change
callback; the manifest's consumes names the two views by the seat (seat:mesh-module-assigner.views.*).

Builds: design 47 G §616, §428, §7
