Module path renamed github.com/prometheus/common → github.com/hanzoai/common. The only functional patch is config/http_config.go: strip conntrack-based dial-context instrumentation, replace with stdlib net.Dialer. This breaks the transitive chain prometheus/common/config → mwitkow/go-conntrack → prometheus/client_golang/prometheus that was leaking into every consumer of prometheus/common/config (alertmanager notifiers, etc.). Functional impact: HTTP clients built via NewClientFromConfig no longer emit go-conntrack connection-tracking metrics (active/closed counters). The connection count is observable via the underlying http.Transport metrics that luxfi/metric ships, so this is loss-of-observability-zero for callers on the Hanzo/Lux stack.
