Split	9ae1bd37fd	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.

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

docs: comprehensive documentation for all modules and handlers

- README.md: full project docs with features, API endpoints, Glicko-2 explanation
- main.rs: doc comments for all 18 HTTP handlers
- db/mod.rs: schema and migration documentation
- models/mod.rs: Player struct and Glicko-2 parameter docs
- Fixed route syntax (:id instead of {id}) for Axum 0.7 compatibility
