Mirrors the azos-core change: azos.claude.enable now sets
azos.agent-memory.backends.claude.enable and
azos.agent-skills.backends.claude.enable instead of the old
azos.claude-memory.enable/azos.claude-skills.enable. The new agent-shell
memory backend needs no wiring here -- it's bundled directly in
azos-core's editor/emacs module, alongside wherever agent-shell itself
gets installed.
