Install opencode in Void rootfs

Browse source 
Bring the experimental Void image closer to the default dev image path by installing pinned mise inside the rootfs build, using it to install opencode, and activating mise automatically for root bash sessions.

Keep the change scoped to the Void builder rather than packages.void so the image still stays language-agnostic at the package-manifest level, then clean mise download/cache artifacts before sealing the rootfs and work-seed.

Extend verify-void so the smoke path now proves mise and opencode are actually present in a fresh void-exp VM. Verified with bash -n make-rootfs-void.sh verify.sh, GOCACHE=/tmp/banger-gocache go test ./..., and make build.
