/**
 * StdinGate is the real GatePort: it prints what the human is approving (tier,
 * issue/stage, commit, and the agent's summary) and reads a y/N answer from
 * stdin. Anything not starting with "y" (case-insensitive) is a decline, so an
 * empty Enter is a safe default-no.
 *
 * Only used by the CLI; validated by the live smoke path, not unit tests (its
 * logic is a thin I/O wrapper — the decision behaviour lives in run-step).
