Wave 2A: offseason data feeds — news wire + quota-disciplined futures

FREE ESPN news wire + championship-winner futures for the never-dark
offseason hub. Both graceful/empty, never fabricate a market value.

- newsService (mirrors injuryService): per-sport ESPN /news FEEDS, pure
  parseNews → { sport, items:[{id,headline,description,published,type,
  athlete?{name,key},team?,href}] }; athlete/team from categories[] only
  (absent when not present). Cache 15m, injectable, offline-tested.
- oddsNormalizer.normalizeOutrights: NEW branch — outrights outcomes are
  {name,price} with no point, so normalizeProps drops them; keeps them with
  best-price-across-allowed-books per selection. + americanToDecimal.
- oddsService.FUTURES_KEYS: separate map (mlb/nba/wnba championship winner),
  OUT of the daily SPORT_KEYS/snapshot budget.
- futuresService: getFutures(sport,deps) → { sport, updated_at, markets:
  [{key,title,selections:[{name,price,prevPrice?,move?}]}] }. One outrights
  call per 12h TTL (quota-disciplined), FUTURES_ENABLED gate. Price-move
  (shortening/drifting/flat) mirrors computeLineDeltas SHAPE on odds not
  line; prev prices persisted inside the futures:{sport} value (no new key).
  linkNewsToMoves pure causal-tie helper.
- Routes /api/news/:sport + /api/futures/:sport (registered) + Next proxies.
- Tests: newsService, futuresService, oddsNormalizerOutrights (fail→pass,
  no network). Full suite green.
