pack.state gave a pack hire only the chief of staff's resolved route, so an
org whose chief has no model refused every hire pack-hire-route-missing. The
route is now the chief's (launch.by), else the org assistant's (the instance
whose definition is assistant; the one named assistant when there are several,
else the first in key order), else null. Both resolve through resolveInstance,
need harness and model, and carry thinking when set. pack.state adds routeFrom,
and each hired or awaiting-owner receipt line carries it. Refusal next step,
CLI hint, WebUI hire reason and the bus, CLI and TOOLS docs say the refusal now
means neither has a route.
