nx_crypto_bench_full.nx

nx_crypto_bench_full.nx -- 1:1 bits-up crypto bench vs OpenSSL incumbent. Measures (us/op, MONOTONIC clock, warmed up): 1. p256_kG_generic -- generic double-and-add k*G (PRE-COMB baseline) 2. p256_kG_comb -- fixed-base comb k*G (BITS-UP path) 3. ecdsa_p256_sign -- full sign (generic kG path; no comb file on box) 4. ecdsa_p256_verify -- full verify (u1*G + u2*Q, real signature) 5. x25519_ecdh -- variable-base scalar mult (shared secret) The comb path here is exercised in-memory via p256_comb_build + p256_scalar_mul_base (same code the deploy signer uses when the /volume1/.../p256_comb.bin file is present), so we get the honest comb-vs-generic SPEEDUP without needing the NAS file on disk.
