Build or refresh the agentic-sandbox QEMU base image so it ships the current agent-client binary, the self-enrolling agent-client.service, the virtio-vsock guest transport, and an up-to-date kernel/libs/tool set. Use when the base image is stale, after an agent-client change, or when wiring the vsock transport (ADR-023/026, #561).
