refactor: rename archzfs to archangel, simplify build-release

- Standardize naming: VM names, hostname, passwords, ISO naming
- Remove USB, Ventoy, and local deployment from build-release
- Add snapper package and Btrfs validation tests to sanity-test
- Update README for dual ZFS/Btrfs architecture
- Delete obsolete SESSION-CONTEXT.md and download-archzfs-iso.sh
