🚀 Feature Request: Multilingual Live Debate with Real-Time Translation

## Description

Currently, DebateAI supports debates in a single language, which limits accessibility and global participation. Introducing Multilingual Live Debate would allow users from different linguistic backgrounds to debate each other seamlessly using real-time translation.

This feature would significantly expand the platform’s reach and inclusivity while leveraging existing AI integrations.

## Proposed Solution

- Enable real-time translation of debate messages so that:
- Each user can select a preferred language
- Messages are automatically translated before being displayed to other participants
- Original messages can optionally be viewed for transparency

## Key Features

🌍 Language selection per user (e.g., English, Spanish, Hindi, French, etc.)

🔄 Real-time translation of debate messages

👁️ Toggle between translated text and original message

🧠 AI-powered translation using LLMs (e.g., Gemini or equivalent)

⚡ Low-latency handling to preserve live debate flow

## Suggested Implementation (High-Level)
### Backend

- Extend debate message pipeline to:
- Detect or accept user language preference
- Translate outgoing messages using AI translation APIs
- Cache translations to reduce repeated API calls
- Add language metadata to debate messages

### Frontend

- Language selector in user profile or debate lobby
- Display translated messages by default
- Optional UI toggle to view original text

## Benefits

✅ Enables cross-language debates
✅ Improves accessibility and inclusivity
✅ Increases global adoption
✅ Strong synergy with AI-driven features

## Potential Challenges

- Managing translation latency
- Ensuring debate context accuracy
- Handling idioms and debate-specific terminology

## Additional Notes

- This feature could later be extended to:
- Multilingual AI challengers
- Language-based matchmaking
- Post-debate multilingual transcripts
