6/// On macOS: delegates to a Lima VM via `limactl shell`.
7/// On native Linux with KVM: runs bash directly on the host.
8/// In the future: could route to OrbStack, UTM, or a remote host.
9///
10/// This trait decouples the "where scripts run" question from the rest
11/// of the codebase. All VM lifecycle, build, and networking code can
12/// accept a `&dyn LinuxEnv` instead of hardcoding Lima.
