/**
 * Plan-mode-info no-op regression (gate tier, paid).
 *
 * Asserts: when /plan-ceo-review is invoked WITHOUT the plan-mode distinctive
 * phrase in the system reminder, the plan-mode-info preamble section is a
 * no-op. The skill should proceed to its normal Step 0 flow with no
 * AskUserQuestion echoing or referencing the plan-mode reminder text.
 *
 * This guardrails the "outside plan mode, this block doesn't interfere"
 * case — a different coverage case from the per-skill in-plan-mode smokes.
 * If the plan-mode-info section ever starts misfiring for non-plan-mode
 * sessions, this test catches it.
 *
 * Cost: ~$0.50 per run. Gated: EVALS=1 EVALS_TIER=gate.
