Adds a single _ENV_OVERRIDES table in default_config.py with type-aware coercion (str/int/bool), so users can switch llm_provider, deep/quick models, backend URL, output language, debate rounds, and the checkpoint flag purely via .env. Centralizes load_dotenv in the package __init__ so the overlay applies for every entry point (CLI, main.py, programmatic). Drops the hardcoded model assignments and duplicate dotenv loads in main.py and cli/main.py. Verified live with OpenAI and Gemini. #602
