/**
 * Protocolink path for deployer gas auto-route: get quote and build tx data for
 * swapping ERC-20 (USDT, USDC, LINK) to native gas (or WETH) on Protocolink-supported chains.
 *
 * Usage:
 *   node scripts/deployment/protocolink-swap-to-gas.cjs --chain-id 1 [--token USDC] [--amount-raw 1000000] [--no-execute]
 *   PROTOCOLINK_API_URL=https://api.protocolink.com node scripts/deployment/protocolink-swap-to-gas.cjs --chain-id 137
 *
 * Requires: Node 18+ (fetch), config/deployer-gas-routes.json for chain list.
 * Output: JSON with quote and tx building instructions; no private key or signing in script.
