Subject: Phase 1.4: Add filesystem selection prompt

- Add FILESYSTEM variable to config (zfs or btrfs)
- Add select_filesystem() function with fzf support
- Update gather_input() to prompt for filesystem in interactive mode
- Add validation for FILESYSTEM in unattended mode
- Btrfs selection errors with "not yet implemented"
- Update banner to show "Archangel" branding
- Update config example with FILESYSTEM option

Groundwork for btrfs support - filesystem choice is now captured,
installation logic gates on FILESYSTEM variable.
