uhash-core

Canonical M1 mining API in this crate is Lithium v1:

UniversalHash(SHA256(miner_address_utf8 || block_hash_32 || cyberlinks_merkle_32) || nonce_le_u64)

Use:

• [lithium_header]
• [lithium_preimage]
• [lithium_hash]
• [meets_difficulty]

Legacy UniversalHash v4 implementation is still present for compatibility tooling (UniversalHash, hash, v4 params), but it is non-canonical for lithium-v1 flow.
