feat(hypervisor): add VM provisioning interface stubs

Add three new methods to HypervisorDriver:
- create_vm_from_cloud_init(): provision VM from template with dual-NIC config
- destroy_vm(): stop and remove VM with optional disk cleanup
- get_vm_status(): poll runtime status, optionally wait for IP via guest-agent

New TypedDicts VMProvisionResultDict and VMStatusDict in models.py
document the provisioning API contract.
