 Expanded CT 302 health check coverage from 3 to 6 monitored servers. Added per-server ssh_user override to health_check.py for servers using non-root SSH (cal@ubuntu-manticore, cal@strat-database). New servers: n8n (10.10.0.210), ubuntu-manticore (10.10.0.226), strat-database (10.10.0.42). Code change: ssh_exec() now accepts optional server_cfg param for per-server ssh_user override. Also fixed: IdentitiesOnly in SSH config, CT 302 host keys for new servers, termix Docker healthcheck (wget->node). Commit: 2b7df76 on cal/claude-runner-monitoring.
