/**
 * plan-ceo-review plan-mode handshake E2E (gate tier, paid).
 *
 * Asserts: when /plan-ceo-review is invoked with the plan-mode distinctive
 * phrase in the system reminder, the skill fires AskUserQuestion FIRST
 * (before any Write or Edit), the question has exactly 2 options (A exit,
 * C cancel), picking "Exit" leads to an orderly exit with no plan file
 * written.
 *
 * Cost: ~$0.50–$1.00 per run. Gated: EVALS=1 EVALS_TIER=gate.
 * Depends on: scripts/resolvers/preamble/generate-plan-mode-handshake.ts,
 * test/helpers/agent-sdk-runner.ts (canUseTool extension).
