zeekay 78767c0e8f rust: add per-algorithm workspace + lux-crypto-{keccak,secp256k1} ...

Establish a Rust workspace at rust/Cargo.toml that admits per-algorithm
canonical bindings to luxcpp/crypto only when the C-ABI returns real
cryptographic output verifiable against published spec vectors.

- rust/Cargo.toml: workspace root with shared edition/license/lints.
- rust/lux-crypto-keccak: canonical binding to lux_keccak256. 12 tests
  asserting byte-equality vs keccak.team / Yellow Paper / eth_hash
  Python (cross-checked) reference values across the empty input,
  short strings, sponge-rate boundary (135 zero bytes), multi-block
  absorption (2048 incrementing bytes), and the 1,000,000-'a' stress
  vector.
- rust/lux-crypto-secp256k1: canonical binding to
  lux_secp256k1_ecrecover{,_batch}. 6 tests asserting byte-equality
  vs eth_keys Python reference values across 3 distinct keypairs and
  the v-low-bit recid convention.
- rust/lux-crypto: umbrella retained for backward compatibility; new
  COVERAGE.md documents 27/27 workspace tests passing and lists
  per-algorithm crates intentionally deferred (sha256, ripemd160,
  blake2b, blake3, ed25519, sr25519, secp256r1, mldsa, mlkem, slhdsa,
  bls, bn254, modexp, evm256, aead, poseidon, pedersen, ipa, verkle,
  kzg, lamport, ntt, poly_mul, frost, cggmp21, corona) until the
  underlying C-ABI bodies stop returning CRYPTO_ERR_NOTIMPL.

Build: CRYPTO_BUILD_DIR=/path/to/luxcpp/crypto/build-canonical
       cargo test --workspace --release
Result: 27 passed, 0 failed, 0 ignored.
