Module metrics 

Metrics collection from Docker containers.

Defines the MetricsCollector trait with implementations:

• BollardMetricsCollector — live stats from bollard
• MockMetricsCollector — test fixtures
• NoopMetricsCollector — no-op for non-metric queries
• MetricRingBuffer — bounded circular buffer for windowed analysis

Example

let collector = BollardMetricsCollector::with_config(Arc::new(docker), &config);
let samples = collector.collect().await?;
