T2.12: Python Action with Dependencies

Tests that Python actions can use third-party packages from requirements.txt,
validating isolated virtualenv creation and dependency management.

Test validates:
- Virtualenv created in venvs/{pack_name}/
- Dependencies installed from requirements.txt
- Action imports third-party packages
- Isolation prevents conflicts with other packs
- Venv cached for subsequent executions
