Improve i18n

[minoneer]

The current i18n system works but could be updated/improved. Some thoughts:

• Paper is rigorously deprecating all string-based messaging/formatting. Sooner or later, we have to switch to Adventure chat.
• Adventure's MiniMessage serialization format may be a good candidate for i18n, as it allows for simple formatting in configs and is extendable.
• There is some translation/i18n support in Paper/Adventure. We may be able to integrate with that. https://docs.papermc.io/paper/dev/component-api/i18n
• Current translation quality varies widely, and we don't support many common languages. AI translations can give a very good baseline nowadays - in conjunction with community-driven https://crowdin.com/.

Closing this umbrella issue.

The main i18n overhaul has now shipped across recent releases:

• 3.2.1 fixed broken translation packaging (

i18n.zip)

• 3.2.2 fixed Spigot lore visibility issues affecting translated challenge/menu display
• 3.3.0 delivered the broader localization update:
  • Adventure/MiniMessage-based message system
  • bundled translations for 50+ languages
  • split translation domains for better prioritization
  • improved item/block/entity name localization
  • /usb lang locale discovery and switching
  • Crowdin integration and updated docs

The main remaining gap has been split into a focused follow-up:

• Localize default challenge text from challenges.yml #114 Localize default challenge text from challenges.yml

That issue covers the remaining untranslated challenge name, description, and reward text coming from challenge config rather than the normal Crowdin/PO pipeline.
