Replace the fixed 8192 MB / 4 vCPU / 20G defaults with the minimum
resources required by the chosen Ubuntu version (libosinfo/osinfo-db
values): 20.04 -> 2048 MB/5G, 22.04 -> 2048 MB/10G, 24.04+ -> 3072
MB/20G. --vcpus now defaults to 2. This stops a small host from being
starved by an oversized default (an 8 GB VM failed to allocate on a
6.7 GB host) and silences the libvirt "less than recommended" warning.
In the todo menu, leaving the RAM/vCPU/disk fields blank now means
"version minimum" (the flag is simply not passed) instead of forcing
8192/4/20G. Any explicit value still overrides. README regenerated.

The script previously required a manually supplied image path and only
installed the client tools, so a bare host aborted at virt-install with
a missing libvirt-sock. It now derives and downloads the Ubuntu cloud
image from --version, detects and installs the full libvirt+QEMU stack
(daemon and system emulator included) through the host package manager,
then enables libvirtd. Adds a --download-only mode, a hypervisor
preflight check, clean error messages instead of Python tracebacks, and
a bilingual usage guide (README).
