MetricsController class

Exposes GET /metrics in Prometheus text format (0.0.4).

Register it via app.enableMetrics() (called after addControllers).

The endpoint returns Content-Type: text/plain; version=0.0.4; charset=utf-8 so Prometheus can scrape it without any extra configuration.

Metrics exposed:

• http_requests_total{method,path,status} — request counter
• http_request_duration_seconds{method,path} — latency histogram
