477a54c548 feat(matchmaker): implement §6.1 Pareto skill-proximity + LRU pairing algorithm
Replace random 2-player pairing with the full §6.1 algorithm:
- Seed selection: bot with oldest last-match timestamp (tiebreak: lowest bot ID)
- Format selection: seed's least-played player count among {2, 3, 4, 6}
- Opponent selection: Pareto 80%/16-rank skill proximity + oldest last-pairing
  with seed + fewest 24h games for game-count balance
- Map selection: least-recently-used active map for the chosen player count,
  with map_scores.last_used_at updated after each match
- Random player slot assignment for all participant counts

7a0de02059 feat(evolver): persist cross-pollination state to Postgres per §10.2
Add crosspoll_state table to persist per-island generation counters

cross-pollination check. Add persistence pattern and translation
structure tests.

0d887ebeb2 fix(starters): fix Java starter HMAC timing attack and code quality
Replace plain String.equals() with MessageDigest.isEqual() for
constant-time HMAC signature comparison. Switch from manual StringBuilder
JSON to Jackson ObjectMapper. Add typed Java records for game state,
moves, and config.
