Phase 1.5: Rename to archangel

- Rename install-archzfs → archangel
- Rename install-archzfs.conf.example → archangel.conf.example
- Update build.sh to use new names
- Update script header with dual-filesystem description
- Update log file names to archangel-*

The installer is now called "archangel" reflecting its expanded
scope: snapshot-based recovery for both ZFS and Btrfs filesystems.
