propose_skill took no strict schema, so a runbook sent under another key
was dropped and the saved one proposed again; the confirm still said
"Saved". Now an unknown key is an error, a change that changes nothing is
refused, and both the bot and the confirm outcome are told which fields
change and whether the runbook is among them.
