 * Regression for the malformed SSH target bug (ISS-0019): extractTargetHost
 * read module_configs.valueJson RAW. valueJson is JSON-ENCODED — a string is
 * stored as `"10.0.20.13/24"` (with quotes) — so splitting on '/' kept the
 * leading quote, producing `root@"10.0.20.13` and a 180s SSH-wait timeout
 * against a container that was actually up. It must parse valueJson.
