Add automated sanity test for ISO verification

New scripts/sanity-test.sh:
- Boots ISO in headless QEMU
- Waits for SSH availability
- Runs 13 automated verification tests:
  - ZFS module loaded and working
  - Custom scripts present (zfsrollback, zfssnapshot, etc.)
  - fzf installed
  - LTS kernel running
  - archsetup directory present
- Reports pass/fail with summary
- Fully automated - no human input required

Updated build-release to use automated sanity test instead of
manual verification prompt.
