vm package (mulga-siv-62):
- Add KernelImage, Initrd, KernelCmdline, FwCfg/FwCfgEntry to vm.Config
- Emit -kernel/-initrd/-append/-fw_cfg args when fields set
- Relax drive invariant: accept kernel image in place of drives
- Add devices.go: IsMMIO predicate, NetDevice/BlkDevice/RngDevice helpers
- Refactor lifecycle.go + network_helpers.go call sites to use helpers
- shutdown.go: os.Remove fw_cfg tmpfiles after QEMU exits
- Add devices_test.go, microvm_test.go; extend vm_test.go
config/input extensions (mulga-siv-63):
- Add MicrovmConfig{ELBv2Enabled, ImagePath} to DaemonConfig
- ImagePath falls back to /usr/share/spinifex/microvm when empty
- Add commented [microvm] section to spinifex.toml template
- Add DirectBoot bool + NICs []NICConfig to SystemInstanceInput
image build pipeline (mulga-siv-64):
- scripts/build-microvm-image.sh: Alpine chroot build producing vmlinuz + initramfs.cpio.gz
- build/microvm/init.sh: fw_cfg-driven PID 1 init (mounts, modprobe, NIC config, lb-agent-env, ca-cert)
- build/microvm/inittab: BusyBox init with lb-agent respawn
- make build-microvm-image target
- setup.sh: install microvm/* to /usr/share/spinifex/microvm/
- .gitignore: exclude built vmlinuz + initramfs.cpio.gz artifacts
