/**
 * Manage a dedicated Python venv at ~/.melaya-runner/venv/ so pipelines

 * (`ModuleNotFoundError: No module named 'shortuuid'`, etc.) on the
 * first pipeline run because agentscope and its 23 transitive deps are
 * not present in the operator's system Python.
 *
 * Idempotent: re-uses the venv if a marker file matches the current
 * shared-bundle version. Re-bootstraps when the bundle version changes.
