avl-auth 0.1.0

//! AVL Platform Integration Example
//!
//! This example demonstrates how AVL Auth integrates with the full
//! Avila ecosystem: AvilaDB, AVX Telemetry, Avila Compress, and more.
//!
//! To run with full features:
//! ```bash
//! cargo run --example avl_platform_integration --features full
//! ```
