Replaces the small cuda-shake-fanout step and the modest kickmix
4x demo with a single dispatch you can feel: 100,000,000 secp256k1
scalar*G batched multiplications.
Numbers measured end-to-end through https://bend.unturf.com/ on
3090-ai:
HTTP request size ~32 bytes (just '(cuda-secp256k1-bench 100000000)')
worker scalar gen 5.2 s (/dev/urandom into 3.2 GB BSCP)
GPU kernel 12.5 s (7.99 Mkeys/s on 3090)
total wall-clock 18.3 s
CPU equivalent ~2000 s = ~33 minutes (libsecp256k1 ref)
speedup-est ~160x
The 3.2 GB of random scalars never crosses the wire — the worker
synthesizes them from os.urandom and dispatches into the existing
cuda-secp256k1-batched-mul daemon. Response is a tiny S-expression
with the timing summary; no 6.4 GB result blob comes back.
Ping + health stay at the top so a visitor sees the chain warm up
before committing to the 18 s heavy run.
