 * Bundle the headless engine + Nostr codecs into a single self-contained ESM
 * file for no-build static sites.
 *
 * The output (`dist/bitgate.js`) is the same canonical code the npm packages
 * ship — not a second implementation — with the bare `@bitgate/*` specifiers
 * resolved and inlined. Consumers copy it onto their own origin and import it
 * with a single relative path; they never fetch it from someone else's
 * deployment.
 *
 * Usage: node packages/standalone/build.mjs [--watch]
