NewGeneratorsFromSeed(seed [32]byte) derives (G, H) deterministically via
RFC 9380 hash-to-curve (SVDW) on BN254 G1, with msg = seed || u64_le(index)
and DST = "LUX_PEDERSEN_SEEDED_GEN_V1". BN254 G1 has cofactor 1, so outputs
are subgroup-correct without clearing.
Existing crypto/rand-backed NewGenerators is unchanged.
Tests: 5 same-seed determinism cases, 5 cross-seed isolation cases, 1
homomorphism check on the seeded basis, 1 frozen golden vector for the
incrementing seed {0..31} so future C++/Rust KAT generators can be cross-
checked against Go byte-for-byte.
