feat: add LingoUI community demo (React wrapper for Lingo.dev SDK)

[YashJsh]

Community Submission: LingoUI

This PR adds LingoUI, a community demo under community/lingo-ui.

LingoUI explores a developer-friendly way to use the Lingo.dev JavaScript SDK in React and Next.js apps by abstracting translation logic behind simple components and hooks.

What this demo shows

• Translating UI text by simply wrapping it with a <Translate> component
• Switching languages at runtime using a LanguageSwitcher
• Server-side usage of the Lingo.dev JS SDK via a Next.js API route
• Graceful fallback behavior when API limits are reached
• No static JSON files or manual i18n configuration

Why this is useful

This demo is intended for:

• Hackathon projects and MVPs
• Teams experimenting with AI-powered localization
• Developers who want minimal setup and clean UI-level integration

Scope

• ✅ Community-only demo
• ❌ No changes to core SDK, CLI, or compiler
• ❌ No production claims — exploratory example only

How to run

Instructions are included in community/lingo-ui/README.md.
