- Split guest-agents/packages.ks into base.ks (qemu-guest-agent) and gui.ks (spice-vdagent)
- Move hypervisor modifier from variant_type.hypervisor to dedicated modifier section
- Added hypervisor modifier with base (headless) and desktop (GUI) options
- Create hypervisor-desktop variant with desktop: gnome for GUI hypervisors
- Update generate_recipe.py to recognize hypervisor-desktop variant name
This ensures GUI packages (virt-manager, spice-vdagent) are only included
in hypervisors with desktop environments, keeping headless hypervisors minimal.
- Replaced individual templates with unified 'install' (desktop, server, hypervisor) and 'live' (live-desktop, live-server) templates
- Added new modifiers: variant_type, hypervisor-type, desktop, initial-setup, virtualization
- Updated generate_recipe.py to handle new modifier structure with additive flags
- Updated recipes_manifest.yaml with new modifier structure
- Added missing fragment files and directories
