feat: skip existing pages on re-run, add --story-slug for targeted repairv0.18.0

- loadOrGenerate() in artist.go skips API calls for pages already on disk,
  loading bytes for the reference chain. Re-runs now only generate missing
  pages instead of regenerating the whole comic.
- --story-slug flag forces the output directory slug so a repair run writes
  to the same directory as the original (e.g. --story-slug ai-jungle-quest).
