/**
 * `tdcv2 pack` — get data packs onto disk without the user hand-managing folders
 * or paths.
 *
 * In a real terminal it opens a small menu: browse the registry, tick the
 * bundles you want, and it downloads, verifies by hash, extracts into the pack
 * store, and wires the store into your config — so the data is usable by its
 * normal address the moment it lands. With no terminal it is scriptable:
 * `pack list` and `pack add <id…>`.
 *
 * Everything lands in ONE tree, at its address path: `<store>/ru/…`,
 * `<store>/countries/russia/…`. Which bundle owns which path is written down in
 * `<store>/.tdcv2-installed.json` rather than implied by a folder name, so ten
 * languages and a hundred countries are one folder and one `dataPaths` entry.
 *
 * The wire (fetch) and the unzip live here; the decisions (what the index means,
 * whether a download is intact, what a bundle owns) are pure in `pack-core.ts`.
 * Inquirer and fflate are imported lazily so the ordinary generate path never
 * pays for them.
