 *
 *   Download Google/Chromium's per-country `ssl-address` postal-address metadata — the
 *   {@link https://github.com/google/libaddressinput libaddressinput} AddressValidationMetadata that
 *   seeds the per-locale field order, required-field, and upper-casing conventions.
 *
 *   See: https://github.com/google/libaddressinput/wiki/AddressValidationMetadata
 *
 *   Replaces the bash `ssl-address-download.sh` (curl + jq). The country list lives at
 *   `…/ssl-address/data` as a `~`-delimited `.countries` string; each country's record is then
 *   fetched from `…/ssl-address/data/<CC>` and written to `<out-dir>/<CC>.json`.
 *
 *   ## Usage
 *
 *   ```sh
 *   mailwoman dev download ssl-address [--concurrency 16]
 *   ```
 *
 *   ## Flags
 *
 *   - `--out-dir <path>` — destination directory; default `./ssl-address` (next to this script)
 *   - `--concurrency <n>` — parallel per-country fetches; default `8`
