Dockerfile: include ego_agent_training + open_ended + teammate_generation (needed for upload ego eval)

API: HF dataset mirror for leaderboard + ckpts; fix ego_fn obs.get bug

API: fix partner not acting (current_player unwrap + simultaneous-step handler), -w 1 to keep sessions, drop difficulty labels

fix gunicorn invocation: single-quote app spec so sh doesn't parse parens

fix CMD: use --factory instead of create_app() (shell was parsing parens as function-def)

re-deploy: study.tsx full play.tsx parity + runtime weight download

deploy: demo viz, prolific study sessions, mini-hanabi, client-eval submit

Add Dockerfile at root for HF Space build
