> Migrate the Guava-shim-based caches in oak-segment-tar from CacheBuilder to OakCacheBuilder.
>   Changes:
>   - SegmentCache — CacheBuilder.newBuilder() → OakCacheBuilder.newBuilder(); Cache → OakCache; Guava RemovalCause → OakRemovalCause; inner Stats class: convert OakCacheStats → Guava shim CacheStats in
>   getCurrentStats() (Guava return type kept until TASK-16)
>   - RecordCache — CacheBuilder.newBuilder() → OakCacheBuilder.newBuilder(); Cache → OakCache; Guava Weigher → OakWeigher
>   - CacheWeights — Weigher → OakWeigher
>   - CachingSegmentReader — update cache type references
>   - Update callers catching ExecutionException to handle CompletionException/RuntimeException
>   Acceptance criteria:
>   - SegmentCacheTest passes
>   - Segment unload timing and eviction callback timing unchanged
