fix(agent): Fix setup and run scripts

- Updated the `run` script to also check if `$OPENAI_API_KEY` is empty before copying `.env.example` and prompting the user to set API keys.
- Modified the `setup` script to install `--extras benchmark` separately from the initial `poetry install` command.
- Added `POETRY_INSTALLER_PARALLEL=false` flag to prevent conflicts between `forge` and `agbenchmark` during installation.
