- Switch MLB standings from deprecated statsapi.mlb.com to ESPN API
(same source as NBA, WNBA, MLS — no auth required)
- Extract shared espn.ts utility: EspnStat/Team/Entry/Group/Response
interfaces, statsMap(), flattenEspnStandings(), parseConferenceRank(),
sortByWinLoss(); removes 4× duplication across adapters
- Fix parseConferenceRank falsy-zero bug (|| undefined → isNaN guard)
- Add stable alphabetical tiebreaker to MLB, NBA, WNBA sort comparators
- Fix winPct silent-zero: fall back to wins/(wins+losses) if ESPN omits stat
- Pre-build statsMap once per entry before sorting in all adapters
- Fix WNBA parseEntry to accept pre-computed sm instead of rebuilding it
- Restore and update gamesBack tests (ESPN returns numeric 0 for leaders,
not the old API's "-" string)

- New WNBASimulator: Monte Carlo (50k sims) projecting remaining regular
season games → seeding → R1 Bo3 / Semis Bo5 / Finals Bo7 bracket
- Hybrid Elo sourcing: pre-season uses futures odds (ICM); once avg
gamesPlayed ≥ 5, switches automatically to SRS-derived Elo
(elo = 1500 + srs × 20)
- New WnbaStandingsAdapter: fetches ESPN standings + teams endpoints in
parallel; includes zero-records for 2026 expansion teams (Portland
Fire, Toronto Tempo) not yet in standings
- Added srs column to regular_season_standings (migration 0063);
stored as net rating proxy (avgPointsFor − avgPointsAgainst)
- Added wnba_bracket to simulatorTypeEnum
