View Source StepFlow.Metrics.LiveWorkerInstrumenter (StepFlow v1.9.0)

Prometheus metrics instrumenter for the LIVE worker lifecycle technical signals (MINT-8248).

Exposes bounded-cardinality counters, consumed by the LIVE AMQP consumers, so that dashboards / alerts and RUN diagnostics can track create / delete events and technical anomalies of live workers. Labels are restricted to small fixed sets to keep the cardinality low (point de vigilance MINT-8248).
