Add an experimental Alpine image flow

Browse source 
Stage a complete Alpine x86_64 image stack so \	--image alpineworks like the existing manual Void path instead of relying on Debian-oriented image builds.\n\nAdd make targets plus kernel/rootfs/register helpers that download pinned Alpine artifacts, extract a Firecracker-compatible vmlinux, build a matching mkinitfs initramfs, seed OpenRC services, and register/promote a managed image named alpine.\n\nFold in the bring-up fixes discovered during boot validation: use rootfstype=ext4 in shared boot args, install libgcc/libstdc++ for the opencode binary, and give opencode more time to become ready on cold boots.\n\nValidate with go test ./..., the Alpine helper builds, image promotion, and banger vm create --image alpine --name alp --nat plus guest service and port checks.
