- Add `scripts/generate-countries.mjs` to enumerate all current ISO 3166-1 alpha-2 codes via CLDR and emit `src/lib/countries-data.ts`; retired, exceptionally-reserved, and CLDR-only pseudo codes are explicitly excluded, XK (Kosovo) is kept - Replace the live `Intl.DisplayNames` calls in `countries.ts` with a direct lookup against the generated `COUNTRY_NAMES` record, eliminating variance between Node/ICU versions - Build the reverse `nameToCode` map from `COUNTRY_NAMES` entries instead of a double-nested loop over the alphabet - Fix `countryCodeFromName` to fall through to `ALIASES` for two-letter inputs that aren't valid codes (e.g. `"UK"` → `"GB"`) - Add `myanmar` / `"myanmar burma"` aliases so the CLDR-style name and the legacy WHOIS variant both resolve to `MM` - Extend `countries.test.ts` to assert pinned names, XK presence, retired/reserved code exclusion, and `UK` alias behaviour
