Adding Custom Metrics to Executors

Custom ExecutionNode executors can record additional metrics via the node execution context:

// In a custom executor — record a domain-specific metric
public override async Task<NodeResult> ExecuteAsync(NodeExecutionContext ctx)
{
    var stopwatch = Stopwatch.StartNew();

    // ... business logic ...

    // Record custom metric
    ctx.Metrics.Record("bizfirst.custom.invoice.processing.duration",
        stopwatch.Elapsed.TotalSeconds,
        new KeyValuePair<string, object?>("invoice.type", invoiceType),
        new KeyValuePair<string, object?>("tenant_id", ctx.TenantId));

    // Increment a custom counter
    ctx.Metrics.Add("bizfirst.custom.invoices.processed",
        1,
        new KeyValuePair<string, object?>("status", "success"));
}
