Introduces internal/provider/kvm with the side-effect-free pieces of the provider: providerID format/parse, the namespaced <metadata> element that carries the GC contract, q35 domain XML over pool volumes, volume XML for overlays and raw seeds, the NoCloud seed ISO built with kdomanski/iso9660, and config defaults. All unit-tested. Step 2 of docs/plans/2026-09-04-1404-kvm-provider.md. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

// Package kvm implements the provider contract on libvirt/KVM hypervisors.
|
|
// Each configured host is reached over SSH with the libvirt unix socket
|
|
// forwarded through the connection, so the hypervisors need no libvirtd TCP
|
|
// or TLS listener and the operator image needs no libvirt libraries. VMs
|
|
// boot a stock cloud image (fetched into the host's storage pool on first
|
|
// use) through a qcow2 overlay, with the Proxy's cloud-init delivered on a
|
|
// NoCloud seed ISO built in-process.
