Adds skyvern run dev and skyvern run ui-dev commands to launch both the API and UI servers in detached background mode, plus a .superset/config.json and helper script to automate Superset workspace setup. This streamlines local development by handling environment syncing, dependency installation, and port conflict resolution without blocking the terminal. However, detached subprocesses with suppressed output may leave orphaned services or hide startup failures, making cleanup and debugging harder.
