# build-release - Build and distribute the archzfs ISO
#
# Usage:
#   ./scripts/build-release              # Full build, test, and distribute
#   ./scripts/build-release --skip-build # Skip build, just distribute existing ISO
#   ./scripts/build-release --skip-test  # Skip sanity test
#
# Distribution targets:
#   - ~/Downloads/isos (always)
#   - truenas.local:/mnt/vault/isos (if reachable)
#   - USB drive with ARCHZFS label (if present, writes via dd)
#   - Ventoy USB drive (if detected, copies ISO file)
