- Move 18 Hyprland/desktop scripts from features/desktop/scripts/ to packaged directories
- Add nomarchy.hardware.fwupd option (default false) and enable service
- Implement nomarchy-update-firmware wrapper for fwupdmgr
- Add hyprland, swayosd, and fwupd to nomarchy-system-scripts dependencies
- Update docs/SCRIPTS.md with 'kept' status for ported scripts
