Remove the anonymous platform image and test cleanup failure.

The workflow records image_id but never removes it. This leaves anonymous pull state in the Docker daemon. It also cannot fail closed when cleanup fails.

  • .github/workflows/llama-cpp-image.yaml#L468-L481: register EXIT cleanup after image_id is available. Remove the validated image_id. Preserve anonymous-config cleanup. Exit nonzero if image removal fails.
  • test/llama-cpp-image-workflow.test.ts#L478-L488: require the image-removal invocation after evidence capture. Add a removal-failure fixture and assert that the capture command fails, so downstream receipt verification cannot run.

As per path instructions, **/*.test.{ts,js,mts,mjs,cts,cjs} requires behavioral confidence rather than implementation lock-in.
