feat(pkgbuild): add anaconda and anaconda-widgets packages with dependency ordering

Add PKGBUILD files for anaconda (45.8) and anaconda-widgets (45.8) to support Fedora's Anaconda installer ported to Arch for FWS with liveimg payload.

anaconda-widgets:
- GTK3 UI widgets with GObject introspection
- Extracted from anaconda source as autonomous autotools project
- Versioned on anaconda release

anaconda:
- Main installer with comprehensive dependency set
- Includes note that further iteration needed on real Arch for buildtime deps and Fedora-specific paths
- Removes widgets files (provided by anaconda-widgets package)

Update setup-aur.sh to build local packages in proper dependency order:
- Define LOCAL_BUILD_ORDER array to ensure leaf packages build first
- anaconda builds last (depends on all other local packages)
- Extract build logic into build_local_pkg function
- Fallback to alphabetical scan for future unlisted packages
- This prevents makepkg -s failures when deps are not yet installed
