 * Effective prompt availability.
 *
 * A prompt may open only when the invocation is interactive — the explicit
 * `--non-interactive` flag wins over `CI` and stdin detection in both
 * directions — and machine output is off. Machine output is an absolute
 * prohibition: a JSON invocation never prompts even from a terminal or with
 * an explicit interaction flag. Every consumer that decides whether to ask,
 * block, or fall back reads this one resolution so planning, approval, and
 * the screen agree.
