Say where a pending merge check is: queued since when, then building on which machine (hq issue 446)

The forge's holder set mesh/merge-gate pending as "the mesh is mapping this head onto its module graph" and nothing
changed it until the verdict, so a ten-minute controller check read as a stalled forge (issue 423). The holder now
says the head waits in the build queue since the local time it was announced; mesh-delivery follows the build
seat's started event and says the machine building it and since when, never over a verdict the forge holds.
