Hold what the tools say to the glossary's retired words (hq ADR 0244)

An agent meets the mesh's words most often in tool descriptions, and
nothing compared them with the glossary: several still said "the host"
for the node-engine and the forge's pull request comment was headed
"Change plan", a word retired twice over. retired-words is the copy of
the words the glossary retires for the tools, and checks/words fails the
repository check when any string a module's code can show, or any
manifest description, uses one. Those found are reworded here.
