feat(releng): add hardware detection and driver setup script

Add fws-setup-hardware script that automatically detects and installs:
- GPU drivers (NVIDIA, AMD, Intel) based on lspci output
- Hypervisor guest tools (VMware, VirtualBox, QEMU, Hyper-V)
- Audio/mic/headset stack (PipeWire), Bluetooth (BlueZ), containers (Podman)
- Optional desktop stack when non-CLI desktop is selected: Steam, Wine, VR support (Monado/OpenXR), and winboat-bin

The script is integrated into the Anaconda kickstart post-installation phase and is non-blocking to prevent installation failures from missing packages or network issues.

Also update profiledef.sh to set correct permissions (755) for the new script.
