zeekay 0c049f1871 rust: ship lux-crypto-poseidon over Poseidon2 t=2 BN254 C-ABI ...

Canonical Rust binding for the Poseidon2 t=2 BN254 Merkle-Damgard
hasher landed in luxcpp/crypto/poseidon. Links statically against
libposeidon.a + libposeidon_cpu.a and exposes:

  hash(input)               -> [u8; 32]
  hash_into(input, output)  -> in-place fill of caller buffer

Byte-equal to upstream gnark-crypto v0.20.1 (NewMerkleDamgardHasher
over NewParameters(2, 6, 50)). 10 spec-vector integration tests
pass, including the canonical 32B/64B/96B block-boundary cases and
trivial avalanche/determinism checks.

Crate is no_std + forbid(unsafe_op_in_unsafe_fn) and follows the
existing per-algorithm crate layout.
