> Introduce CacheAccessService as a unified entry point for:
> 	•	cache lookup (read path)
> 	•	cache population (read miss, write path, prefetch, compaction)
> Refactor:
> 	•	HFileReaderImpl
> 	•	write path components (HFile writer, bloom/index writers)
> Goal:
> 	•	remove topology-specific logic from read/write paths
> 	•	centralize cache interactions
> No behavior change expected.
