fix(data): adopt ISO short names — Czechia, Cabo Verde

[dmythro]

What

Updates two countries to their official ISO 3166 / UN short English names, and aligns the Czech native to its matching short form:

Code	name (before → after)	native (before → after)
CZ	Czech Republic → Czechia	Česká republika → Česko
CV	Cape Verde → Cabo Verde	already Cabo Verde (no change)

Why

Consistency with the short-name policy already applied to Türkiye, Kyiv, Eswatini, and North Macedonia. "Czechia" (ISO/UN since 2016) and "Cabo Verde" (ISO/UN since 2013) are the current official English short names.

ISO 3166 defines names only in English and French — it has no native-language field — so native is the dataset's own field. Česko is the official Czech short form (the native equivalent of "Czechia"), chosen to match the short English name and the dataset's short-native convention (e.g. Germany/Deutschland). CV native was already the short, untranslated Cabo Verde.

⚠️ Behavior change (reverse name lookup)

getCountryCode() matches on name/native, so the old strings no longer resolve:

getCountryCode('Czech Republic')   // false (was 'CZ')
getCountryCode('Česká republika')  // false (was 'CZ')
getCountryCode('Cape Verde')       // false (was 'CV')

getCountryCode('Czechia')          // 'CZ'
getCountryCode('Česko')            // 'CZ'
getCountryCode('Cabo Verde')       // 'CV'

Worth a changelog note. Shipping in the same minor as the currency data updates.

Sources

Official ISO 3166 / UN short names — not arbitrary edits, and consistent with names the dataset already uses for the same reason (e.g. Türkiye per ISO 3166).

CZ → "Czechia" / "Česko" — "Czechia" registered in UN UNTERM/UNGEGN (5 Jul 2016) and added to ISO 3166 (Sep 2016), alongside the formal "the Czech Republic". ISO carries only the English/French name; the UN recognises Česko (short) / Česká republika (formal) as the Czech names:

• UN UNGEGN country record — English short Czechia, formal the Czech Republic
• ISO 3166 OBP — CZ (English short Czechia; no native field)
• Czech MFA — "Czechia"/"Česko"

CV → "Cabo Verde" — the Republic of Cabo Verde asked the UN (24 Oct 2013) to use "Cabo Verde" in all official languages, untranslated; ISO 3166 follows UN usage:

• UN member-state page — "Cabo Verde"
• ISO 3166 OBP — CV

📝 Walkthrough

Walkthrough

Two country entries are updated in packages/countries/src/data/countries.ts: CV changes from “Cape Verde” to “Cabo Verde”, and CZ changes from “Czech Republic” to “Czechia” with native changing from “Česká republika” to “Česko”. A new getCountryCode() test case covers the updated short-name lookups and checks that the former long-form names now return false.

Poem

🐇 I nibbled the names and set them aright,
Cabo Verde and Czechia now read just right.
Short names hop in, old names hop out,
The code and the test now agree, no doubt.
Hoppity-hoppity, data shines bright!
