Variables
Delete variable (remove from prompt or purge)
mode=remove_from_prompt (default) removes {{name}} from the system prompt and leaves the variable + per-installation values intact. mode=purge is irreversible: soft-deletes the variable and cascades to all hub-client values. Purge requires body {"confirmation":"EXCLUIR"}.
