Fix vm run guest checkout ownership

Browse source 
Extract the host worktree overlay with tar -o so the guest repo stays owned by root instead of inheriting host UID/GID metadata. That avoids Git's dubious ownership check on /root/<repo> after vm run.\n\nAlso register the guest checkout as a safe.directory during repo setup so opencode and manual git commands can read branch state reliably after attach.\n\nValidation: GOCACHE=/tmp/banger-gocache go test ./... and make build.
