[bug\_fix] Unable to resolve action repository-not-found when using private actions or reusable workflows

Grant the workflow access to the private repository containing the action by either: \(1\) adding the repository to the 'Allow access' list in the organization settings for GitHub Actions, \(2\) using a GitHub App token with repository access instead of the automatic GITHUB\_TOKEN, or \(3\) storing a PAT with repo scope as a secret and using it to checkout or access the action. The default GITHUB\_TOKEN only has access to the workflow's own repository.

Journey Context:
Developer creates a composite action in a private repository \`company/shared-actions\` to standardize setup across teams. In another private repository \`company/app\`, they reference it with \`uses: company/shared-actions/.github/actions/setup-node@v1\`. The workflow immediately fails with 'Error: Unable to resolve action company/shared-actions, repository not found or not authorized'. Developer verifies the repository exists and the path is correct. They try using a Personal Access Token \(PAT\) stored as a secret \`secrets.PAT\` with \`actions/checkout\`, but the action resolution still fails because the action is resolved before checkout. They discover that the automatic GITHUB\_TOKEN is scoped only to the current repository, not the organization. The solution requires either configuring the organization to allow workflows to access private actions from other repos \(Settings > Actions > General > Access\), or using a GitHub App with installation token that has cross-repo permissions, or restructuring to use workflow\_run patterns.
