feat: more switch image coverage + system health metrics + Erik monitor
switch-image-fetcher: - Add Fortinet URL builder (11 FortiSwitch models) - Add Quanta Cloud Technology, Allied Telesis, Ufispace, Netgear URL builders - Fix alcatel-lucent-enterprise slug missing from URL_BUILDERS dispatcher - Fix NVIDIA builder to skip ConnectX/BlueField adapters (not switches) - Add aruba slug alias for hpe-aruba health endpoint: - Add system metrics: CPU load (1/5/15m), memory usage, disk usage - Add load_status indicator (ok/busy/overloaded) - Expose process RSS memory - Used by external monitors scripts/monitor-erik.sh: - Cron-ready health check script for Claudi (.82) and Raspberry Pis - Checks TIP API health endpoint (load, memory, disk, DB latency) - Checks PM2 process state via SSH (errored/stopped detection) - ntfy.sh push notifications (set NTFY_TOPIC env var) - Includes systemd service + timer unit comments for auto-install
