Curator: Efficient Vector Search with Low-Selectivity Filters

Summary: Curator targets low-selectivity filtered ANNS, where graph indexes fragment after predicate pruning and degree-boosting fixes are too costly. It uses a dual-index, partition-based design with label-specialized indexes inside a shared clustering tree, preserving graph-based performance while adding incremental updates and complex predicates with little overhead.
