feat(loldle): add emoji and quote champion-guessing modules

Ship two new loldle-family modules mirroring loldle.net's non-classic
modes. Text-only MVP (ability/splash phases stay deferred).

- loldle-emoji: 5 guesses, emoji-sequence clue. Pool derived algorithmically
  from classic's champions.json metadata (species/region/resource mapping
  table) since loldle.net's bundle has no static emoji pool.
- loldle-quote: 6 guesses, lore-blurb clue. Pool seeded from Data Dragon
  champion title + first lore sentence; champion name redacted to ___.
- scripts/fetch-ddragon-data.js: single generator for both JSONs.
- src/util/normalize-name.js: shared lookup helper; loldle/lookup.js
  refactored to import it.

35 new tests (484 total passing). Lint clean.
