Virtualenv — docker-free local Python execution

Standalone install? If this session was not initialized by the TAO skill bank plugin, run the tao-setup skill first (host preflight, credentials, cross-skill discovery).

The virtualenv platform runs a Python script natively in an existing venv — as an argv vector whose first element is <venv>/bin/python, never through a shell, never activating anything. The vendored runner (references/virtualenv_runner.py) is this platform's "native CLI" — the role docker/kubectl/sbatch play elsewhere — and owns only the process lifecycle. Job records stay with tao_job_record.py; specs are authored by the agent, exactly like every other platform.
