feat: auto-run setup when virtual environment is missing

- Update run_gemini.sh to automatically run setup.sh if venv doesn't exist
- Update run_gemini.bat to automatically run setup.bat if venv doesn't exist
- Remove fallback to system Python - always use venv for consistency
- Provide clear error messages if setup fails

This ensures users don't see "ModuleNotFoundError" - instead the server
will automatically set up dependencies on first run.
