Assigner: hears build.ended and version-released, reads no build log; a want's version and parts come from them

A kept build's or another branch's build names its parts and keeping node from build.ended; the trunk's entry names its version and parts from the version-released whose source is the kept assignment graph revision's. The parts' contract comment says <module>:<artifact>.

Builds: design 47 G §379, §525, §526, A-94, A-96, A-67
