arqen 0.3.0

//! # Arqen
//!
//! Backend infrastructure for agent-ready applications.
//!
//! Arqen provides a complete backend toolkit including:
//! - HTTP server with Axum (feature: `http-server`)
//! - thingd integration for storage, events, search, and queues (feature: `thingd-native`)
//! - Typed agent tools and manifest generation
//! - Durable job workers with graceful shutdown
//! - Structured logging with tracing (feature: `logging`)
//!
//! ## Quick Start
//!
//! ```rust,ignore
//! use arqen::http::{create_router, start_server};
//! use std::net::SocketAddr;
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync>> {
//!     let addr: SocketAddr = "127.0.0.1:3000".parse()?;
//!     let router = create_router();
//!     start_server(addr, router).await?;
//!     Ok(())
//! }
//! ```
