Two new no_std crates wrapping the C-ABI from luxcpp/crypto/ntt and
luxcpp/crypto/poly_mul.
lux-crypto-ntt:
* forward / inverse — generic-prime NTT (caller-supplied modulus + root)
* Cyclone-FFT fast path engaged automatically when (modulus, root) ==
(Q=998244353, PRIMITIVE_ROOT=629671588)
* 6 spec-vector tests:
- forward+inverse roundtrip across n in {2,4,...,1024}
- q97/omega=28 generic-prime roundtrip (matches Go reference)
- input rejection: empty, non-pow2, modulus=0
lux-crypto-poly_mul:
* multiply / multiply_into — Z_Q[X]/(X^n+1) negacyclic convolution
* Pinned to Cyclone-FFT prime (the C-ABI rejects other rings)
* 4 spec-vector tests including the canonical 10-case KAT table
(sum/first/last byte-equal to luxfi/crypto/poly_mul Go reference)
and the (1+2X+3X^2+4X^3)*(5+6X+7X^2+8X^3) hand-written negacyclic case.
build.rs links statically against libntt_cpu.a / libpoly_mul_cpu.a
produced by luxcpp/crypto/ntt and luxcpp/crypto/poly_mul; CRYPTO_BUILD_DIR
or CRYPTO_DIR points at the cmake build / install layout.
Verified: cargo test -p lux-crypto-ntt -p lux-crypto-poly_mul
6/6 ntt tests PASS, 4/4 poly_mul tests PASS.
