Help translate CapRust — new languages welcome

[Domica]

CapRust currently ships English + Croatian, and Spanish, Italian and German are landing now (Fluent-based, runtime switching, no restart).

If you are a native speaker of any of these — or want to add a new language (French, Portuguese, Polish, Turkish, …) — here's how:

1. Copy crates/i18n/src/locales/en.ftl → xx.ftl (your language code) and translate the values. Keep keys, { $placeholders } and comments intact.
2. Register it in crates/i18n/src/lib.rs: add to BUNDLES, extend LANGUAGES, and extend the matches! filter in detect_locale.
3. Full guide: TRANSLATING.md.
4. Open a PR — a second speaker reviewing is appreciated but not required.

Note: untranslated keys render as the raw key, so even a partial translation is useful and easy to spot-check in Settings → Appearance → Language.

Reply here with the language you want to take, so two people don't duplicate work.
