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`.

mcp ps now uses the actual container image and version from the runtime
instead of the registry, which could be stale after a failed deploy.
Deploy now returns an error when the component filter matches nothing
instead of silently succeeding with zero results.

All import paths updated to git.wntrmute.dev/mc/. Bumps mcdsl to v1.2.0,
mc-proxy to v1.1.0.

Extract ContainerNameFor and SplitContainerName into names.go.
ContainerNameFor handles single-component services where service
name equals component name (e.g., mc-proxy → "mc-proxy" not
"mc-proxy-mc-proxy"). SplitContainerName checks known services
from the registry before falling back to naive split on "-", fixing
mc-proxy being misidentified as service "mc" component "proxy".
Also fixes podman ps JSON parsing (Command field is []string not
string) found during deployment.

Critical fixes:
- Wire monitor subsystem to agent startup (was dead code)
- Implement NodeStatus RPC (disk, memory, CPU, runtime version, uptime)
- Deploy respects active=false (sets desired_state=stopped, not always running)
Medium fixes:
- Add Started field to runtime.ContainerInfo, populate from podman inspect
- Populate ComponentInfo.started in status handlers for uptime display
- Add Monitor field to Agent struct for graceful shutdown
