Story 1+2 from Firecracker PRD. Adds: - guest-runner.sh: poll loop inside Firecracker VM that watches .joelclaw-microvm/run.signal, executes command.sh, writes result.json - Dockerfile.rootfs: COPY guest-runner into image - build-rootfs.sh inittab: respawn guest-runner + debug shell on ttyS0 Protocol: host writes command+signal → guest executes → writes result → host polls. No bashisms — POSIX sh compatible with busybox. Handles timeout via request.json timeoutMs field. Auto-restarts via busybox init respawn.
