- Implement ML-DSA-65 (FIPS 204) using cloudflare/circl * Single implementation with automatic CGO optimization * Sign ~440μs, Verify ~130μs, KeyGen ~165μs on M1 Max * All 11 tests passing - Simplify ML-KEM implementation * Remove redundant optimized versions * Use circl ML-KEM-768 directly - Simplify SLH-DSA implementation * Remove premature optimizations * Clean stub for future circl support (FIPS 205) - Add comprehensive cache package * LRU cache from luxfi/node * Metercacher for metrics integration * Test utilities - Add crypto utils * Atomic operations * Bytes utilities * Complete utils package from luxfi/node - Update secp256k1 and BLS * All BLS tests passing (23 tests) * secp256k1 fuzz test added All post-quantum implementations now use cloudflare/circl as single source of truth, following DRY principle and ensuring FIPS compliance.
