 * npm-bin shim (`dist/bin/vidbee.mjs`).
 *
 * The published artifact is the standalone npm tarball — Desktop no
 * longer bundles the CLI (NEX-148). `--vidbee-local` requires the bundled
 * `@vidbee/task-queue` and `@vidbee/downloader-core`; the bundler inlines
 * them. `better-sqlite3` is left external so the npm consumer installs it
 * as an `optionalDependency` only when crash-recovery is wanted.
