/**
 * keep-cli.mjs - Interactive CLI for keeping KidLisp pieces on Tezos
 * 
 * Features:
 * - Shows AC user info and wallet status
 * - Previews the piece and artifact
 * - Uploads to IPFS with progress
 * - Connects to Temple via Beacon P2P
 * - Resumes from any stage if interrupted
 * 
 * Usage:
 *   node keep-cli.mjs <piece-code>
 *   node keep-cli.mjs puf
 *   node keep-cli.mjs puf --resume ipfs    # Resume from IPFS upload
 *   node keep-cli.mjs puf --preview        # Preview artifact only
