- 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)

* Add MLS standings sync and fix simulator conference resolution
- New MlsStandingsAdapter using ESPN's free soccer API (no key required),
returning Eastern/Western conference data, W/D/L/GF/GA/GD/PTS, conference
rank, and home/away records; registered under mls_bracket
- Display route now shows soccer table columns and a 9-team playoff cutoff
line for mls_bracket (top 9 per conference qualify for MLS Cup Playoffs)
- MLS simulator gains a third conference fallback: reads externalId="Eastern"
or "Western" on the participant, mirroring the LLWS pool-assignment pattern
so admins can bootstrap conference data before the first standings sync
- 9 unit tests covering stat mapping, conference normalization, rank ordering,
and error paths

* Address code review feedback on MLS standings + simulator
1. Update mls-simulator.ts module comment to document the new step-3
externalId fallback in the conference resolution order
2. Tighten normalizeConference to exact-match "Eastern"/"Western
Conference" instead of broad substring, preventing false matches
on names like "Northeast"
3. Pre-parse statsMap for each entry before the sort so it isn't
rebuilt O(n log n) times during comparison
4. Document the externalId name-matching tradeoff on
parseConferenceFromExternalId
5. Try ESPN's gamesPlayed stat before falling back to wins+losses+ties
sum; export parseConferenceFromExternalId for direct testing
6. Add tests: normalizeConference passthrough, winPct=0 at preseason,
and parseConferenceFromExternalId (case-insensitivity, null/undefined,
numeric ESPN IDs, unrecognized strings)

* Fix lint: replace != null with !== null && !== undefined
oxlint enforces eqeqeq; the five != null checks in mls.ts were flagged.
