Add orb and sun VMs with virtiofs swarm-common share

- Add orb (192.168.122.183) and sun (192.168.122.184) to inventory
- Create host_vars for orb and sun (fresh install, brew_packages: [])
- Add brew_packages to zap host_vars (gogcli, himalaya, kubernetes-cli, opencode)
- customize.yml: parameterize brew_packages via host_vars, add /mnt/swarm-common
  virtiofs+bindfs mount for all VMs, install bindfs, fix Homebrew install
- provision-vm.yml: remove become requirement; use virsh vol commands for all
  disk/image operations (no sudo needed)
- roles/vm/tasks/main.yml: rewrite disk provisioning to use virsh vol-create-as
  and vol-upload; fix vol name quoting for names with spaces; use qcow2 backing
- domain.xml.j2: always include swarm-common virtiofs share; make main share
  conditional on vm_virtiofs_source/tag
