/**
 * `emdash-plugin build`
 *
 * Thin citty wrapper around `buildPlugin` from `./api.js`. Produces the
 * on-disk dist artifacts for an npm-installed sandboxed plugin:
 *
 *   - `dist/plugin.mjs` (+ `.d.mts`) — runtime bytes (hooks + routes).
 *   - `dist/index.mjs` (+ `.d.mts`) — descriptor module, bare default export.
 *   - `dist/manifest.json` — normalised manifest, kept in sync.
 *
 * Plugin authors run this from their package's `prepublishOnly` (or a
 * `pnpm build` script that delegates). Bundling for the registry (the
 * tarball form) is a separate command — see `emdash-plugin bundle`.
