- Add crates/rutster/src/metrics.rs with metrics_router(),
metrics_handler, and render_prometheus_text().
- Add config::metrics_bind() parser for RUTSTER_METRICS_BIND
(default 127.0.0.1:9090).
- Spawn the /metrics listener in main.rs on its own tokio task,
above the TLS/plaintext branch.
- Add integration tests covering the 503 path and the live media
thread 200 path.
- Emit rutster_event_sink_drops_total only when the sink reports a
concrete count; omitting the line avoids misleading zero-drops readings.
