refactor: simplify ChainResolver and RayCaster interfaces, enhance ChainDamageApplier logic

- Updated ChainResolver to remove unused shooterOrigin and shooterDirection parameters, streamlining the resolve method.
- Modified RayCaster interface to reflect changes in method signature, focusing on maxBlocks only.
- Enhanced ChainDamageApplier to utilize a new CauseIndexHolder for resolving the PHYSICAL damage cause index, improving clarity and performance.
- Refactored ChainDamageApplier.apply method to use HytaleEntityAdapter for target references, ensuring correct damage application.
- Adjusted tests in ChainResolverTest and ChainDamageApplierTest to align with the new method signatures and logic.

Tests: All tests passing. Build: ./gradlew clean build successful.
