//! examples/async_multi_sensor.rs
//!
//! Demonstrates running multiple independent `AsyncAnomalyzer` detectors
//! concurrently — one per sensor stream — using `tokio::join!`.
//!
//! Each sensor has its own baseline and anomaly characteristics:
//!   - temperature: subtle drift then a sharp spike
//!   - pressure:    stable, then a gradual climb
//!   - vibration:   noisy but bounded, then a violent burst
//!
//! Run with:
//!   cargo run --example async_multi_sensor --features async
