/**
 * Builds model messages for Agent Signal nightly self-review.

 * Use when:
 * - A server reviewer asks the model to convert a bounded digest into self-review drafts
 * - Tests need the stable prompt contract without importing server runtime code
 *
 * Expects:
 * - `context` is already private-safe and bounded by the caller
 *
 * Returns:
 * - A system/user message pair ready for structured object generation
