Jeremy Tregunna 68283a5fed feat: implement merged iterator across all levels with improved tombstone handling ... - Remove redundant MergedIterator (was just an alias for HierarchicalIterator) - Add IsTombstone method to all iterators to detect deletion markers - Enhance tombstone tracking in compaction manager with preservation options - Fix SSTable reader to properly handle tombstone entries - Update engine tests to directly verify tombstone behavior - Update TODO.md to mark merged iterator task as complete		2025-04-19 22:18:12 -06:00
