Implements the hypervisor design's Phase 1: a second runtime.Runtime
backend (QEMU) that runs each service component as a Nanos unikernel VM
instead of a podman container, selected per-component via a new
runtime = "unikernel" service-def field.
- internal/runtime/qemu.go: QEMURuntime. Pull extracts the ELF from the
OCI image; Run does `ops build` + boots qemu-system-x86_64 with KVM,
user-mode net port-forwards, QMP control socket and serial console log;
Stop/Remove/Inspect/List/Logs map onto VM lifecycle + state dir.
- proto/registry/servicedef: add runtime, memory_mb, vcpus fields
(registry migration 5).
- agent: holds both runtimes; runtimeFor() selects per component;
listAllContainers() merges containers + VMs so drift/status see both.
Unikernel runtime auto-enables on nodes with /dev/kvm + ops.
Validated end-to-end on straylight: a test service deploys via
`mcp deploy --direct`, boots as a Nanos unikernel, serves HTTP through
the agent port-forward, and reports running via `mcp status`/`mcp logs`.

New agent RPCs for v2 multi-node orchestration:
- SetupEdgeRoute: provisions TLS cert from Metacrypt, resolves backend
hostname to Tailnet IP, validates it's in 100.64.0.0/10, registers
L7 route in mc-proxy. Rejects backend_tls=false.
- RemoveEdgeRoute: removes mc-proxy route, cleans up TLS cert, removes
registry entry.
- ListEdgeRoutes: returns all edge routes with cert serial/expiry.
- HealthCheck: returns agent health and container count.
New database table (migration 4): edge_routes stores hostname, backend
info, and cert paths for persistence across agent restarts.
ProxyRouter gains CertPath/KeyPath helpers for consistent cert path
construction.
Security:
- Backend hostname must resolve to a Tailnet IP (100.64.0.0/10)
- backend_tls=false is rejected (no cleartext to backends)
- Cert provisioning failure fails the setup (no route to missing cert)
