> h2. Description
> Refactor *HFileReaderImpl* to use *CacheAccessService* as the entry point for block cache access instead of directly interacting with *BlockCache*.
> This change updates the read path to delegate cache operations through CacheAccessService, including:
> * block lookup on read
> * cache population on read miss
> * cache-related metrics updates (if applicable)
> h3. Scope
> * Replace direct BlockCache calls in *HFileReaderImpl* with *CacheAccessService*
> * Adapt existing call parameters to use request/write context objects
> * Ensure compatibility with current caching behavior
> h3. Notes
> * No behavior change intended
> * Existing cache implementations (*LruBlockCache*, *BucketCache*, *CombinedBlockCache*) remain unchanged
> * CacheAccessService implementation continues to delegate to BlockCache in this phase
> * This is part of migrating read path code toward a pluggable cache architecture
