/**
 * VeChain Clause Builder Utility
 *
 * VeChain supports multi-clause transactions, allowing multiple operations
 * in a single transaction. This is powerful for:
 * - Batch transfers to multiple addresses
 * - Multiple contract calls in one transaction
 * - Atomic operations across contracts
 * - Gas efficiency (shared base cost)
 *
 * Each clause contains:
 * - to: recipient address
 * - value: VET amount in wei
 * - data: encoded data for contract calls
