- Added a history management system in model.py to store and retrieve recent messages from Chat, Mic, and Speaker. - Updated controller.py to automatically add messages to the translation history after processing. - Enhanced translation clients (OpenAI, Gemini, Groq, etc.) to accept and utilize context history for improved translation quality. - Introduced YAML configuration options for enabling history injection and customizing its behavior across different translation models. - Ensured that only original messages are stored in history to optimize token usage during translation.
