Cal Corum d1619b4a1f CLAUDE: Phase 3 - Substitution System Core Logic
Implemented comprehensive substitution system with DB-first pattern:

## Core Components (1,027 lines)

1. SubstitutionRules (345 lines)
   - Validates pinch hitter, defensive replacement, pitching change
   - Enforces no re-entry, roster eligibility, active status
   - Comprehensive error messages with error codes

2. SubstitutionManager (552 lines)
   - Orchestrates DB-first pattern: validate → DB → state
   - Handles pinch_hit, defensive_replace, change_pitcher
   - Automatic state sync and lineup cache updates

3. Database Operations (+115 lines)
   - create_substitution(): Creates sub with full metadata
   - get_eligible_substitutes(): Lists inactive players

4. Model Enhancements (+15 lines)
   - Added get_player_by_card_id() to TeamLineupState

## Key Features

-  DB-first pattern (database is source of truth)
-  Immutable lineup history (audit trail)
-  Comprehensive validation (8+ rule checks)
-  State + DB sync guaranteed
-  Error handling at every step
-  Detailed logging for debugging

## Architecture Decisions

- Position flexibility (MVP - no eligibility check)
- Batting order inheritance (pinch hitter takes spot)
- No re-entry (matches real baseball rules)
- Validation uses in-memory state (fast)

## Remaining Work

- WebSocket event handlers (2-3 hours)
- Comprehensive testing (2-3 hours)
- API documentation (1 hour)
