Add WNBA playoff simulator with SRS-based Elo ratings, fixes #125 (#231)
* Add WNBA playoff simulator with SRS-based Elo ratings, fixes #125

- 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
