Hanzo AI 45f209d740 rename keccak/ → keccak256/ — package name names the variant, like secp256k1
The package is Keccak-256 only (Size=32, all Sum* functions return
[32]byte). Naming it 'keccak' was misleading — Keccak is a family
(256/384/512). Now matches the secp256k1 precision pattern.

Function renames drop redundant '256' suffix:
  Sum256       → Sum
  Sum256Hex    → SumHex
  Sum256Batch  → SumBatch

Call sites read:
  import "github.com/luxfi/crypto/keccak256"
  h := keccak256.Sum(data)
