Introduce a Vagrantfile-like declarative config format using KDL for defining
multi-VM environments. Includes KDL parsing with validation, a provisioning
engine (shell inline/script + file upload over SSH), and four new CLI commands
for managing VM lifecycles from VMFile.kdl definitions.

Unified VM management consolidating QEMU-KVM (Linux) and Propolis/bhyve
(illumos) backends behind an async Hypervisor trait, with a vmctl CLI for
direct use and a library API for orchestrators.
- Core library: types, async Hypervisor trait, miette diagnostic errors
- QEMU backend: direct process management, raw QMP client, QCOW2 overlays
- Propolis backend: zone-based VMM with REST API control
- Shared infra: cloud-init NoCloud ISO generation, image download/cache,
SSH helpers with retry
- vmctl CLI: create, start, stop, destroy, list, status, console, ssh,
suspend, resume, image pull/list/inspect
- nebula-vm zone brand: lifecycle scripts and platform/config XML for
illumos zone integration
