/**
 * `emdash-plugin bundle`
 *
 * Thin citty wrapper around `bundlePlugin` from `./api.js`. The interesting
 * logic lives there; this file only handles arg parsing, consola formatting,
 * and process exit on errors so the rest of the CLI can `await` it cleanly.
 *
 * If you're building tooling on top of bundling, import `bundlePlugin`
 * directly -- this command is the terminal-output adapter, not the API.
