Phase 1.1: Create lib/ directory structure for archangel refactor

- Add custom/lib/common.sh: output, validation, fzf prompts, disk utils
- Add custom/lib/config.sh: argument parsing, config loading, validation
- Add custom/lib/disk.sh: partitioning, EFI management, disk selection
- Add custom/lib/zfs.sh: pool, datasets, ZFSBootMenu, services, hooks
- Update install-archzfs to source libs
- Remove duplicated output/config functions from main script

Prepares codebase for btrfs filesystem support (Phase 2).
