%description
Sovereign Hardware Abstraction Layer (HAL) providing high-performance CUDA
kernels for GPU-accelerated WSPR (Weak Signal Propagation Reporter) data
processing. Fat binary supports RTX 5090 (sm_100), RTX 40xx (sm_89),
RTX 30xx (sm_86), and Ampere A100 (sm_80).

Features:
- Zero-copy pinned memory allocation
- Async host-to-device and device-to-host transfers
- CUDA stream management for pipelined processing
- WSPR spot validation kernel
- Vectorized processing kernel (normalize + validate + convert)
- GPU-based deduplication kernel
- Callsign sanitization kernel

Optimized for 10+ billion row WSPR datasets with RTX 5090 (32GB VRAM).
