EIP-8355 Proposes ML-DSA Verification Precompiles at NIST Levels II, III, V

EIP-8355 (PR #12048) proposes three precompiles verifying FIPS 204 ML-DSA signatures at NIST levels II, III, V (sets 44/65/87). Concatenated input: pubkey ++ signature ++ message. Returns 1/0, never reverts. Four divergences: adds levels III/V, variable-length messages, compressed 1312/1952/2592-byte keys, no alterations. Addresses, gas costs placeholder. Currently draft.
