//! VM lifecycle management.
//!
//! Provides `epkg vm` subcommands for managing VM sessions:
//! - `vm start` - Start a VM for an environment (all platforms)
//! - `vm stop` - Stop a running VM (all platforms)
//! - `vm list` - List running VMs (all platforms)
//! - `vm status` - Show VM status (YAML) (all platforms)
//!
//! Session management (session.rs) is used by VM backends (libkrun, qemu) for
//! cross-platform VM discovery. This is needed on all platforms where VM backends run.
//!
//! Guest daemon (guest_daemon.rs) runs inside the VM to handle commands from host.
