Add new fws-hw-detect script that detects hypervisor type and GPU hardware, outputting either machine-readable environment variables for kickstart processing or human-readable French text summary for live environment.
The script serves as the single source of truth for hardware detection, consumed by:
- Live environment display via zenity before installation starts
- Anaconda %post chroot to apply appropriate guest tools and GPU drivers
Supported hypervisors: VMware, VirtualBox, QEMU/KVM, and physical machines
Supported GPUs: NVIDIA, AMD, Intel, and VMware/VirtualBox virtual graphics
No hard dependencies; gracefully degrades when lspci and ip are unavailable.
