agentic-eval 0.14.2

//! Benchmark VM / sandbox systems for **agentic AI use** — the spawn-and-tear-down
//! sandbox loop an agent runtime drives (one isolated environment per tool call).
//!
//! Ranks AetherVM against Firecracker, Cloud Hypervisor, gVisor, Kata, QEMU/KVM,
//! and Docker on five agent-native axes (start-latency, density, isolation,
//! snapshotting, agent-control), then shows a head-to-head and the evidence.
//!
//! Run: `cargo run -p agentic-eval --example vm_benchmark`
