StarRocks Optimization: Null Filtering + Bloom Index Cuts 12s Query to 1s, Fixes CN Restarts

A StarRocks case study shows how early null filtering and Bloom indexes reduced a 200M-row query from 12s to under 1s while eliminating CN node OOM restarts through predicate pushdown and partition pruning.
