Merge main into feat/47-G-join11: the tool runner's mesh/stream.publish (issue 1979)

The capability stream-publish is stated under mesh-sdk's word (buscalls.StreamPublishWord) and in the runtime artifact's states, so G's test that the stated words are the manifest's states holds; the publish uses G's exported JetStream.

Builds: design 47 G §545, §622; design 42 zfs-owns-zfs A-42, A-44
