Load env vars in Node.js

Use Node 22+ built-in env loading so config stays out of source:

process.loadEnvFile?.();


const rpcUrl = process.env.SOLANA_RPC_URL;
const privateKey = process.env.WALLET_PRIVATE_KEY;


if (!rpcUrl || !privateKey) {
  throw new Error('Missing SOLANA_RPC_URL or WALLET_PRIVATE_KEY');
}
