High-performance parallel save/load for large NumPy

●●SolidBig BrainShip It
Zero-copy shared memory beats pickle for large arrays, but Zarr already does parallel chunks.
Strengths
- •Standard library multiprocessing and shared memory avoid heavy external dependencies.
- •Zero-copy data sharing between processes reduces serialization overhead significantly.
- •Preserves dictionary keys and array metadata through dedicated sidecar files.
Weaknesses
- •No benchmarks prove speedup over standard np.save or established Zarr.
- •Fragmented file output lacks atomicity and chunking of established formats.
