👋 Hi @Jelledb! This PR has been linked to the Feature Shipping Tracker: BuildingBlockRunner API (meshBuildingBlockRunner meshObject) (meshcloud/janny#1025) under DoD item 6 (Reference Examples Updated).

The noop backplane for Google Cloud Run and the e2e runner test you are adding here directly address the open meshstack-hub example we have been tracking for the self-hosted runner workflow. 🎉 Merging this will help close out that DoD item.

Pull request overview

This PR extends the meshstack/noop building block to support dispatching runs to a dedicated meshStack “building block runner” and adds an E2E test fixture that provisions a Cloud Run–hosted runner backplane and executes the noop building block against it.

Changes:

• Add optional runner_ref wiring to the noop building block definition (version_spec.runner_ref).
• Introduce a new GCP Cloud Run “backplane” module that provisions secrets, an API key, and registers a meshStack runner.
• Add a new E2E runner test module + tftest.hcl run that provisions the backplane and asserts noop run outputs.
