A clean clone had no runnable backend and no instructions to create one —
the GUI README assumed platform/.venv existed and still described the
desktop shell as future work. Add setup_dev_env.sh (venv + editable
coworker install + the aisuite .pth this checkout's import wiring needs,
verified by booting the server to a 200 health check) and rewrite the
README's from-source flows: browser two-terminal dev and tauri dev, which
already falls back to the venv server when no packaged sidecar exists.
