fix(quickget): validate architecture support after edition selection

- Skip early architecture check for OSes with editions_<os> to avoid
  rejecting valid edition-specific combinations
- Perform architecture validation after EDITION is known and show a
  descriptive error when the chosen edition isn't available on ARCH
- Preserve test/show behaviour (report SKIP) and keep previous flow for
  OSes without editions_<os>
