v0.9.3: Add .env config, auto-load env vars in shared/config.py

- Add .env with LLM_PROVIDER, OLLAMA_MODEL, HF_MODEL defaults
- shared/config.py auto-loads .env (with or without python-dotenv)
- Dashboard reads LLM_PROVIDER from env for provider selection
- HF Space uses HF_TOKEN secret + auto fallback to free model
