[bug\_fix] Composite action fails with 'Unrecognized named-value: inputs' or cannot access secrets/context inside composite action steps

Explicitly define the input in the composite action's \`inputs\` metadata section, then reference it inside the action using \`$\{\{ inputs.input-name \}\}\`. For secrets, they must be passed as inputs from the caller workflow \(e.g., \`with: token: $\{\{ secrets.MY\_SECRET \}\}\`\); the composite action cannot access the \`secrets\` context directly. Root cause: Composite actions run in the caller's context but have isolated metadata; they must declare their interface explicitly, unlike reusable workflows which inherit contexts differently.

Journey Context:
A developer creates a composite action to standardize a deployment step. In the \`action.yml\`, they define steps that use a token. They try to access it via \`$\{\{ secrets.DEPLOY\_TOKEN \}\}\` directly in a \`run\` line, or they try to use \`$\{\{ inputs.token \}\}\` without having defined an \`inputs\` section in the composite action metadata. The workflow fails immediately with "Unrecognized named-value: 'secrets'" or "Unrecognized named-value: 'inputs'". The developer is confused because reusable workflows \(called with \`uses: ./.github/workflows/reusable.yml\`\) \*can\* access \`secrets\` if passed with \`secrets: inherit\`. They research and find that composite actions are distinct from reusable workflows. The fix is to add an \`inputs\` section at the top of \`action.yml\` defining \`token\` as a required input, then update the calling workflow to pass \`secrets.DEPLOY\_TOKEN\` as an input parameter \(\`with: token: $\{\{ secrets.DEPLOY\_TOKEN \}\}\`\). Inside the composite action, they reference the value via \`$\{\{ inputs.token \}\}\`. This explicit interface ensures the secret is securely passed through the input boundary rather than being accessed via the global context, which is restricted in composite actions.
