refactor(ci): split scrape and sync into two workflows

- update-champions.yml: cron/manual only, scrapes + commits
  champions.json. Uses LOLDLE_PAT so the push retriggers sync.
- sync-champions.yml: runs on push to champions.json (or manual
  dispatch), fans out to downstream repos via the sync_repo helper.

Single responsibility per workflow; chained via the push trigger.
