/**
 * plan-ceo-review plan-mode smoke (gate, paid, real-PTY).
 *
 * Asserts: when /plan-ceo-review is invoked in plan mode, the skill reaches
 * a terminal outcome that is either:
 *   - 'asked'      — skill emitted its Step 0 numbered prompt (scope mode
 *                    selection, or the routing-injection prompt that runs
 *                    before Step 0)
 *   - 'plan_ready' — skill ran end-to-end and surfaced claude's native
 *                    "Ready to execute" confirmation
 *
 * FAIL conditions: silent Write/Edit before any prompt, claude crash,
 * timeout.
 *
 * Replaces the SDK-based test that never worked: the SDK's canUseTool
 * interceptor on AskUserQuestion never fires in plan mode because plan
 * mode renders its native confirmation as TTY UI, not via the
 * AskUserQuestion tool. The real PTY harness observes the rendered
 * terminal output directly.
 *
 * See test/helpers/claude-pty-runner.ts for runner internals.
