[bug\_fix] Unrecognized named-value secrets or failed secret access in reusable workflow

Explicitly pass secrets to the reusable workflow using the \`secrets\` keyword in the caller workflow, either by mapping them individually \(\`secrets: MY\_TOKEN: $\{\{ secrets.MY\_TOKEN \}\}\`\) or by using \`secrets: inherit\` to pass all secrets automatically \(requires specific repository settings\). The root cause is that reusable workflows \(workflow\_call\) run in a separate context and do not automatically inherit secrets from the calling workflow's environment, even if the caller has access to them. Each secret must be explicitly wired through the interface contract.

Journey Context:
You refactor a monolithic workflow into a reusable workflow to share logic across multiple repositories. The original workflow authenticated to an external service using \`secrets.API\_TOKEN\`. After extracting the logic into a separate workflow file with \`workflow\_call\` trigger, and calling it from the original workflow using \`uses: ./.github/workflows/reusable.yml\`, the job fails with 'Input required and not supplied: token' or an error indicating that \`secrets\` is undefined in the reusable workflow context. You verify that the calling workflow has access to the secret by printing a masked version in a step before the reusable workflow call, confirming the secret is available in the caller context. You suspect a syntax error in the reusable workflow definition and check the inputs section, which looks correct. After searching GitHub Issues for 'reusable workflow secrets undefined', you discover that reusable workflows do not inherit secrets from the calling workflow by design, as they represent a distinct security boundary. The debugging reveals that the \`secrets\` context in a reusable workflow only contains secrets explicitly passed via the \`secrets\` keyword in the \`uses\` statement of the caller. The fix works because explicitly mapping the secret creates a contract between the caller and the reusable workflow, or using \`secrets: inherit\` passes the entire secrets context through the interface, allowing the reusable workflow to access the necessary authentication tokens.
