StudioRunnerTools called directly: list, run, and refusal semantics
===================================================================
The runner's tools are plain methods, so a platform can call them without a
wielding model. This example builds two published components, lists them, runs
one by id, and shows the registry guard: a runner constructed without the
registry refuses to run a component whose stored config references
registry-backed resources, because the rebuild would silently drop them.
Dispatch resolves only published versions; creates pass publish=True here (the
draft-inert behavior is demonstrated in registry_and_components.py).
Prerequisites: OPENAI_API_KEY
Run: .venvs/demo/bin/python cookbook/05_agent_os/22_studio/studio_runner_direct.py
Try: pass registry=registry to the second runner and watch the refusal clear
