Add internationalization (i18n) support and initial English / Brazilian Portuguese translations

[cookieukw]

Introduce a lightweight i18n system and initial translation files so UI texts can be localized. Adds a t() helper, loads translations, and replaces/organizes several UI strings into translation keys. No breaking changes.

Added

• en.json — English translation keys (initial)
• pt-BR.json — Brazilian Portuguese translations (initial)
• i18n.ts — simple translation resolver t(path) with fallback to English

Modified

• formats.ts — uses t(...) for format names/descriptions and registers category translation.
• Several UI labels and messages updated to use translation keys (examples: plugin.title, menu.import_attachment, textures.message, actions.hytale_add_quad, toggle.toggle_attachment_editing, settings.*)

Testing / QA 🔧

• Load plugin in Blockbench (dev build) and confirm UI texts render from translations (e.g., format names, import dialog text) ✅
• Change Language.code (or Blockbench language) to pt-BR and verify Portuguese strings appear ✅
• Set an unsupported language code to verify English fallback behavior ✅
• Verify newly added translation keys are present in en.json and have equivalents in pt-BR.json ✅

Notes for reviewers / maintainers 📝

• No breaking changes; existing behavior remains when translations are missing (fallback to English).
• New translation keys should be kept in sync across languages; consider adding a validation script to CI to detect missing keys (suggestion for follow-up)
• To add more languages, add src/translations/.json matching en.json key structure and import it in i18n.ts
• Release note (one line) 📣
• Added i18n support with initial English and Brazilian Portuguese translations and a t() helper for localized UI strings

This is of great importance to me, as I am not familiar with either English or Brazilian.

Yes, it's also possible to add other languages ​​in the future. It's not one of the best systems, but it serves its purpose very well

I am not Brazilian but this seems really important because I know one of the major countries with Hytale fans is Brazil, I think this could help make Hytale modding more accessible to a lot of people who enjoy the game.
