reachableceo 6c5ba3d8c6 feat: restore test-iso.sh with fixes for local libvirt execution ...

Restore the libvirt/virsh ISO testing script that was deleted in commit
c1d8c5d ("will fold into run.sh" but never was). run.sh still references
test-iso.sh via the test:iso command, so it must exist.

The original script had several issues preventing it from running on
this host. This commit restores it from git history (commit 241510c)
with the following fixes:

- Disk path: Changed from /var/lib/libvirt/images/ (root-owned) to
  ./tmp/ (writable by user), avoiding permission denied errors
- CPU model: Changed from deprecated "host" to "host-model" per
  virt-install warning
- Graphics: Simplified from Spice with channel to plain VNC, fixing
  "virtio-serial-bus: A port already exists" error
- Networking: Removed --network flag (no libvirt default network
  available on this host; not needed for ISO boot testing)
- Sudo: Removed unnecessary sudo from qemu-img and rm commands
  (user is in libvirt group and disk is in local tmp/)
- Startup: Removed redundant virsh start after virt-install (which
  already starts the domain), fixing "Domain is already active" error

Commands:
  ./run.sh test:iso create    Create and boot test VM from ISO
  ./run.sh test:iso console   Connect to VM serial console
  ./run.sh test:iso status    Show VM status
  ./run.sh test:iso destroy   Stop and remove VM

Tested: VM boots successfully from the 450M ISO artifact.
