Merge pull request 'Repo guards (repolist) + PeaZip flavor guard' (#14) from fix/repo-and-peazip-guards into main

Two nits from YuKu's laptop paste: the 100-space line wipe left a
visible gap before short summaries (now ANSI EL: \r\033[K, no
residue), and '(0 packages)' printed when nothing new was installed
(idempotent re-run / theme deps all present) — the count parenthetical
is now omitted when zero.
