Portrait stays on biz-monitor; cutover create/ensure owns purpose=cutover_hf slots with project collect override, multi-interval bindings, window pause, and industrial detail UX. Also expand ZTE collect/config parsers and TextFSM for route/BGP/L2VPN/VRRP coverage. Co-authored-by: Cursor <cursoragent@cursor.com>
