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`.

Skip empty lines from the scanner that result from double newlines
(application slog trailing newline + container runtime newline).

New server-streaming Logs RPC streams container output to the CLI.
Supports --tail/-n, --follow/-f, --timestamps/-t, --since.
Detects journald log driver and falls back to journalctl (podman logs
can't read journald outside the originating user session). New containers
default to k8s-file via mcp user's containers.conf.
Also adds stream auth interceptor for the agent gRPC server (required
for streaming RPCs).
