feat: improve setup script robustness

- Add automatic PostgreSQL service start if not running
- Add graceful handling of existing configs when venv creation fails
- Check for existing configs in /etc/aitbc before failing on venv error
- Provide manual recovery instructions when venv creation fails
- Change pyproject.toml error to warning to allow setup to continue
- Improves hermes agent setup experience by handling partial failures
