The previous approach accumulated per-game deltas into season stats rows,
which was fragile — partial processing corrupted stats, upsert bugs
compounded, and there was no self-healing mechanism.
Now update_season_stats() recomputes full season totals from all StratPlay
rows for each affected player whenever a game is processed. The result
replaces whatever was stored, eliminating double-counting and enabling
self-healing via force=True.
Also fixes:
- evolution_evaluator.py: broken PlayerSeasonStats import → queries
BattingSeasonStats or PitchingSeasonStats based on card_type
- evolution_evaluator.py: r.k → r.strikeouts
- test_evolution_models.py, test_postgame_evolution.py: PlayerSeasonStats
→ BattingSeasonStats (model never existed)
