- Replace the `config.py` module with a new `settings.py` to streamline environment variable management, focusing on database, CORS, and TURN settings. - Update references throughout the backend codebase to use the new `settings` module instead of the deprecated `config`. - Modify the `.env.example` file to reflect the new configuration approach, indicating that model provider credentials should be maintained separately. - Enhance the `AssistantConfig` model to clarify the source of runtime connection information, ensuring it is injected from model resources rather than relying on defaults from the environment. - Introduce new user scripts for audio and video management in the Tampermonkey environment, enhancing WebRTC capabilities.
