getConfiguredHostIPs() and the new discoveryConfigSnapshot() now deep-copy config under a brief RLock and release it before resolving Proxmox/PBS/PMG hostnames via the injectable lookupConfiguredHostIP seam, so slow or blocked DNS can no longer stall monitor writers. The discovery IPBlocklist is the deduplicated merge of the operator-configured blocklist and the resolved configured-host IPs. Adds lock-freedom and merge coverage tests; updates the monitoring contract obligation.
