AQD: Online Adaptive Query Dispatcher for HTAP Databases

Summary: AQD: HTAP query dispatcher for dual-engine row/column systems, targeting ultra-low-latency routing under workload drift. Offline LightGBM + self-paced Taylor-weighted boosting, then online LinTS-Delta adaptation with Mahalanobis resource balancing; integrated into PolarDB, >90% latency reduction.
