Remove Calamares compilation and configuration, replace with Anaconda installer setup.

Changes:
- Remove Calamares-related entries from .gitignore
- Update README with migration status from Calamares to Anaconda
- Rename setup-calamares.sh references to setup-aur.sh
- Remove Calamares packages from package lists
- Add anaconda and liveimg payload packages
- Add Anaconda kickstart configuration (interactive-defaults.ks)
- Update boot sequence documentation: remove Calamares desktop selection, simplify to Openbox live environment
- Remove Calamares-specific troubleshooting entries
- Clean up .xinitrc and .zlogin to remove Calamares launcher
- Update build scripts to reference local repo generically instead of Calamares-specific

setup-aur.sh
