motivation

In GitHub Actions reusable workflow, we likely combine two phases: run go test -coverprofile=out then collect coverage report.

For example:

    - uses: actions/setup-go@v5
      with:
        go-version: stable
    - run: go test -race -covermode=atomic -coverprofile=prof.out ./...
      shell: bash
    - k1LoW/octocov-action@v1

In this situation, I think, there is a structural problem.

1. .octocov.yml may be stored on the caller repository
2. on the other hand, resuable workflow will likely be stored another repository, such as octocat/workflows
3. so we must sync coverage.report paths in the two or more repositories:
   • go test of the reusable workflow
   • .octocov.yml for each repository
