feat(battle-sim): implement battle simulation logic and metrics tracking

- Added WarBattleMetrics interface to track attacker and defender skills during battles.
- Enhanced WarUnit class with method to log activated skills.
- Introduced environment setup for battle simulation, including unit set loading and configuration resolution.
- Developed in-memory and Redis transport layers for handling battle simulation requests and results.
- Created types and interfaces for battle simulation payloads and responses.
- Implemented battle simulation processing logic, including logging and skill tracking.
- Added tests for battle simulation processor to ensure functionality and correctness.
