*	Phase 1.4: Add filesystem selection prompt	Craig Jennings	2026-01-23	2	-0/+33
\| \| \| \| \| \| \| \| \| \| \| \| \|	- 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.
*	Fix set -e compatibility in lib functions	Craig Jennings	2026-01-23	3	-3/+9
\| \| \| \| \| \| \| \| \|	- Replace [[ ]] && error pattern with if/then/fi - Pattern causes exit when condition is false with set -e - Fixed in: common.sh, config.sh, disk.sh, install-archzfs Discovered during VM testing: the && short-circuit returns exit code 1 when condition is false, triggering set -e to abort.
