Add TPEN-side sender workflow for shared OpenAPI artifact sync to cubap/rerum_openapi

[Copilot]

This PR adds TPEN-services as the canonical editing surface for the shared OpenAPI artifact and automates export into cubap/rerum_openapi via PR updates. It establishes a standard provider path in this repo while keeping consumers anchored to the receiver repo artifact, and aligns the sync implementation with current OpenAPI seam rollout conventions.

• Canonical provider artifact (TPEN-owned)

  • Added openapi/components/tpen-services-shared-components.openapi.yaml as the source-of-truth shared contract artifact in a discoverable OpenAPI components layout.
  • Normalized artifact baseline metadata/structure for seam rollout consistency (OpenAPI version, contract version, provider metadata, and components.schemas stub).

• Sender sync workflow (cross-repo PR automation)

  • Added .github/workflows/sync_tpen_shared_openapi.yaml.
  • Triggers on:
    • pushes to development that touch the shared artifact
    • manual workflow_dispatch
  • Behavior:
    • checks out cubap/rerum_openapi
    • copies TPEN provider artifact to schemas/openapi/tpen-services-shared-components.openapi.yaml
    • opens or updates an automation sync PR branch in the receiver repo
    • uses standardized seam-rollout PR branch/message conventions and OPENAPI secret token

• Repo-level guardrails for sync scaffolding

  • Extended existing existence checks to assert both:
    • openapi/components/tpen-services-shared-components.openapi.yaml
    • .github/workflows/sync_tpen_shared_openapi.yaml
  • Added focused test coverage in __tests__/openapi_sync_artifacts.test.js to validate:
    • provider artifact baseline structure
    • workflow sync configuration

Updated in commit 3eb83b3 to align with current seam rollout conventions: standardized sync workflow conventions (token, branch naming, PR metadata), normalized shared artifact baseline fields, and added focused scaffolding tests for the sync artifact/workflow contract.

Pull request overview

This PR introduces TPEN-services as the canonical source for a shared OpenAPI components artifact and adds automation to sync that artifact into cubap/rerum_openapi via an auto-updating pull request workflow.

Changes:

• Added a new shared OpenAPI components provider artifact under openapi/components/.
• Added a GitHub Actions workflow to copy the artifact into cubap/rerum_openapi and create/update an automation PR.
• Extended database-independent existence/scaffolding tests to assert the new artifact and workflow exist, and added a focused test for baseline content.
