fix: set sdk: docker in README (was streamlit, caused CONFIG_ERROR on HF)

Force rebuild on HF Spaces

Add variable tree: section/question/item hierarchy from 3176-var survey

Add Docker config for Hugging Face Spaces deployment

Add Streamlit config: disable XSRF, set max upload size

Fix: use getvalue() not read(), drop session_state to fix AxiosError on Cloud

Add debug output during upload to diagnose Cloud issue

Rewrite: clean state management, no rerun loop, tabs layout

Initialize session state explicitly, force rerun after load

Fix upload: read bytes eagerly, show errors explicitly

Add system dependencies for pyreadstat
