amberjs 1.17.0

// Grafana Dashboard Integration Module
//
// This module provides comprehensive Grafana dashboard integration for Amber runtime:
// - Dashboard management and configuration
// - Real-time metric visualization
// - Custom chart and graph rendering
// - Grafana API integration
//
// # Examples
//
// ```rust
// use amberjs::observability::dashboard::{
//     DashboardManager, DashboardConfig, PanelConfig,
//     GrafanaClient, ChartRenderer, GraphRenderer, TemplateEngine
// };
//
// # async fn example() -> Result<(), Box<dyn std::error::Error>> {
// let config: _ = DashboardConfig::default();
// let manager: _ = DashboardManager::new(config).await?;
//
// // Create a new dashboard
// let dashboard: _ = manager.create_dashboard("amberjs-overview")?;
//
// # Ok(())
// # }
// ```
