Serve OpenPI Policy

Start one local OpenPI inference server and finish with a verified endpoint for an Arena Pi0RemotePolicy client. Keep Experiment execution, artifacts, OSMO, and other policy providers outside this skill.

Read the checked-out workflow

Before acting, read:

• docs/pages/quickstart/running_a_real_policy/openpi.rst for the maintained two-terminal workflow, first-run costs, and readiness message.
• isaaclab_arena_openpi/docker/run_openpi_server.sh for the supported flags and current variant mapping.

Treat the current checkout as the source of truth. Use the wrapper rather than reconstructing its Docker command or calling build_server_image.sh directly. Report any mismatch between this skill, the documentation, and the wrapper.
