MERKLE_ALLOWLIST_BUILD @ 1.1.0

Merkle allowlist builder (standard-v1 tree format)

Builds an OpenZeppelin StandardMerkleTree (standard-v1, sorted leaves, double-keccak leaves) from up to 5,000 rows, default [address, uint256] or your own elementary leafEncoding, and returns the root plus per-entry proofs verifiable with OpenZeppelin MerkleProof (up to 1,000 proofs per call; page larger lists with proofOffset; the root always covers every row). Duplicates are flagged. Example request: {"entries":[["0x1111111111111111111111111111111111111111","5000000000000000000"],["0x2222222222222222222222222222222222222222","2500000000000000000"]]} gives root 0xd4dee0beab2d53f2cc83e567171bd2820e49898130a22622b10ead383e90bd77.
