Cap the cores-per-row group size (and the dashboard 'g' cycle) by total core
count so the toggleable-row count stays sensible and small machines get finer
control: ≤4 cores toggle individually (size 1), 5-8 cores in groups of up to 2,
and more than 8 in groups of up to 4. The cap is also the default — the prior
fixed default of 4 now clamps to the tier (1/2/4), and an explicit
--cpu-group-size is clamped to the cap too.
Add max_group_size() in cpu_groups; update the help text and the cpu_groups /
control tests (the cycle test now uses 16 cores so it can exercise sizes 4/2/1).

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.
