[bug\_fix] Input required and not supplied: token or authentication failures in reusable workflows accessing secrets

Explicitly pass secrets to the reusable workflow using secrets: inherit to pass all secrets, or secrets: with named mappings \(secret-name: $\{\{ secrets.secret-name \}\}\) to pass specific secrets. Reusable workflows run in their own isolated context and do not automatically inherit secrets or variables from the caller workflow. The GITHUB\_TOKEN must also be explicitly passed if the reusable workflow needs repository permissions.

Journey Context:
A development team creates a reusable workflow for deploying applications to AWS. The reusable workflow is defined in .github/workflows/deploy.yml and uses workflow\_call with inputs and secrets defined \(aws-access-key-id, aws-secret-access-key\). The workflow steps use these secrets to configure AWS credentials. In a caller repository, a developer calls this reusable workflow using uses: org/shared-workflows/.github/workflows/deploy.yml@main and passes inputs, but doesn't specify any secrets section. The workflow fails with "Input required and not supplied: aws-access-key-id" or similar. The developer checks that the caller repository has the secrets defined in its Settings > Secrets, and confirms they exist. They try adding env variables but that doesn't help. Searching documentation, they discover that reusable workflows are isolated from the caller's secret context for security reasons. Secrets must be explicitly passed using the secrets keyword in the caller. The developer modifies the caller to add secrets: inherit \(since they want to pass all secrets with matching names\) or explicitly maps secrets: aws-access-key-id: $\{\{ secrets.AWS\_ACCESS\_KEY\_ID \}\}. The reusable workflow now receives the secret values and successfully authenticates with AWS.
