Health report — SUMMARY/YYYY-MM/HEALTH_timestamp.csv / .html

Generated by --healthcheck. One row per device: CPU %, memory %, virtual-chassis state (Catalyst StackWise/VSS, Nexus vPC, Alcatel VC), and a threshold-evaluated status OK / WARN / CRIT / ERROR. The HTML version is the same table with color-coded status cells, sorted worst-first — suitable as an email body via --notify.
