//! Routing from inside your process: the flow carries @device(vm1) with
//! host = "local", so this run spawns the local Bark VM — the worker's
//! REAL compute core — exactly as `maned-run` would.
//!
//! Requires the maned toolchain installed (it provides `bark-vm` on PATH):
//! curl -fsSL https://fabianodicheti.github.io/maned/install.sh | sh
//!
//! cargo run --example routed
//!
//! Expected output:
//! r = shape [2, 2], data [19, 22, 43, 50]
