//! GPU Storage Layer — Optional acceleration using CUDA.
//!
//! Provides utilities to transfer Arrow RecordBatches to GPU memory
//! and execute custom kernels.
//!
//! ## Advanced Optimizations (007)
//!
//! - **CUDA Streams**: Asynchronous data transfer and kernel execution overlap
//! - **Multi-GPU**: Distributed processing with NVLink support
//! - **Histogram Optimization**: Fast aggregation for small cardinality keys
//! - **Unified Memory**: Automatic memory management with prefetching
//! - **Persistent Kernels**: Reduced kernel launch overhead
