G sessions: the runner serves a bundle's put and get sessions and states put-sessions

A value over buscalls.ChunkBytes is put by mesh/objects.put-chunk (written into the module's store as each chunk is
taken, sealed on the last, dropped at its bound or a disorder) and got by mesh/objects.get-chunk after a chunked answer,
for a state's object and a sent object alike; the 8 MiB BundleObjectMost cap is gone with the stateobjects constant.

Builds: design 47 G §518, §345, §457, §490, §620, §622, A-21, A-25
