/**
 * StdinPrompt is the real PromptPort: it prints a question and reads the answer
 * from stdin. `confirm` treats anything not starting with "y" as a decline, so a
 * bare Enter is a safe default-no — matching StdinGate's posture. `select`
 * prints a numbered menu and reads a choice; a bare Enter (or any unrecognised
 * input) selects the first option, which callers pass as the safe default.
 *
 * Used only by `diablo init`; validated by the live init path, not unit tests
 * (the decision logic lives in init-diablo, tested against a fake prompt).
