DART: A Lock-free Two-layer Hashed ART Index for Disaggregated Memory

Summary: DART: lock-free, crash-consistent two-layer hashed ART for disaggregated memory. Uses a hashed upper skip table + in-node adaptive hash layout to cut remote round trips and confine search to small buckets, boosting concurrency/scalability up to 5.8x on YCSB.
