Module prometheus 

Local Prometheus collectors for supervisor metrics.

Compiled only when the prometheus feature is enabled. The collectors live in a process-local Registry (NOT the prometheus crate’s default global registry, so host services that already own a registry don’t collide with us). Hosts that want to expose these metrics call registry() and either:

• Serve registry().gather() directly from their /metrics handler, or
• Use prometheus::Registry::register on each individual collector to merge them into the host’s own registry.

The atomic counters in SupervisorMetrics remain the authoritative in-process source of truth; this module just mirrors them into Prometheus-shaped collectors.
