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.
