Initial commit: jackpotminer Equihash 192,7 miner

GPU-accelerated Equihash 192,7 miner in Rust with three solver backends:
- CPU: Wagner's algorithm, AVX2 packed slots (xenoncat-style)
- OpenCL: full on-GPU solve (kernels/equihash.cl); runs on NVIDIA and AMD
- CUDA: driver-API replay of miniZ's extracted fatbin (src/miniz/)

Also includes a default-off pearlhash backend (src/pearl/, native CPU core +
NVRTC int8-GEMM GPU kernels) and a WIP Ethash CUDA backend (src/ethash/).

Reverse-engineering scratch (alpha-miner, pearl-dump/) and the active runtime
config (mine.toml) are gitignored; mine.example.toml is the template.
