- Renamed old columns to _deprecated_*
- Created recalculate_ratings.rs tool to replay all matches
- Updated all queries and structs to use unified rating
- Match form now shows single rating per player
- API returns single rating field

Final ratings after recalculation:
- Andrew: 1538

Refactor: Implement all four ELO system improvements

CHANGES:

1. Replace arbitrary margin bonus with per-point expected value
   - Replace tanh formula in score_weight.rs
   - New: performance = actual_points / total_points
   - Expected: P(point) = 1 / (1 + 10^((R_opp - R_self)/400))
   - Outcome now reflects actual performance vs expected

2. Fix RD-based distribution (backwards logic)
   - Changed weight from 1.0/rd² to rd²
   - Higher RD (uncertain) now gets more change
   - Lower RD (certain) gets less change
   - Follows correct Glicko-2 principle

3. Add new effective opponent calculation for doubles
   - New functions: calculate_effective_opponent_rating()
   - Formula: Eff_Opp = Opp1 + Opp2 - Teammate
   - Personalizes rating change by partner strength
   - Strong teammate → lower effective opponent
   - Weak teammate → higher effective opponent

4. Document unified rating consolidation (Phase 1)
   - Added REFACTORING_NOTES.md with full plan
   - Schema changes identified but deferred
   - Code is ready for single rating migration

All changes:
- Compile successfully (release build)
- Pass all 14 unit tests
- Backwards compatible with demo/example code updated
- Database backup available at pickleball.db.backup-20260226-105326
