feat(vz): set descriptive window title for VZ VMs using the graphical display

Let's label the VZ GUI windows so it's easy to tell which window each VM is using.

StartGraphicApplication accepts a vz.WithWindowTitle option via the
Code-Hex/vz library. This passes a title of the form "Lima: <name>
(<arch>)" so users can identify which VM owns a given window at a
glance — useful when running multiple VMs simultaneously.
