v0.49.0

Minor Changes

• 482c2db Thanks @constLiakos! - Reference catalogs per ADR-0024: ./countries is now the complete officially assigned ISO 3166-1 alpha-2 list (249 entries, CLDR English names, code-derived flags, GB — not UK — for the United Kingdom, plus findCountry/pickCountries/countryDisplayName), and a new ./languages subpath ships the ISO 639-1 superset (43 entries with nativeName endonyms and optional flags, plus findLanguage/isLanguageCode/pickLanguages/languageDisplayName). No alias maps or normalization shims — clean break. scripts/export-catalogs.mjs emits the backend-facing JSON templates. ProviderForm's country field now uses the library Combobox (searchable, clearable — the catalog is ~250 entries) instead of a native <select>; the countryOptions contract is unchanged, with new optional countrySearchPlaceholder/countryEmptyLabel/countryClearLabel label props.
