DeroStorm 1.5.2 - Fill the GPU

Fill the GPU. The batch now uses the VRAM it already had, and mining sits at four suffix blocks per SM instead of sweeping up to 1,252.

GPU

--gpu-batch=0 already claimed to size the launch from free VRAM; the library still launched 8,192 hashes, which left stage 1 and SHA on half-empty SMs. It now fills the card, capped at 32,768 so job latency stays under about half a second. On a 5080 that is 30,016 hashes a batch, ~350 ms, and 85.87 KH/s at 336 suffix blocks against 74.9k at 8,192.

Stage 1 writes each 256-byte append as sixteen-byte stores.

Mining defaults to four suffix blocks per SM (the occupancy this kernel actually reaches) instead of sweeping from a few KH/s up through 1,252, which measured slower under a display. --bench still sweeps. Pin --gpu-blocks=336 on a 5080 if you want the same number in the logs.

Windows and Linux GPU archives both ship the new kernels (fat cubins, Turing through Blackwell).
