RenderMetricsProgramMonitor class final

Program interceptor that forwards render-monitor aggregates into overlays.

This wraps ProgramRenderMonitor and publishes formatted key/value entries through RenderMetricsInjector, so widget apps can surface runtime render activity without duplicating monitor plumbing in each example or host app.
